There are many methods of heat treating a part to potentially make it harder. These include quenching, precipitation hardening (ageing), case hardening and carburising, which are offered through our digital network.

The Brinell test is typically used for materials with a coarse or granular microstructure, such as cast iron, aluminium, and soft metals. It provides a reliable measurement of hardness but may not be suitable for very hard or thin materials due to the large indentation size.

It's important to note that the Rockwell hardness scales are dimensionless numbers and are used to represent the hardness of a material based on the depth the indenter penetrates the material. The higher the Rockwell hardness number, the harder the material. Additionally, different Rockwell scales are used for different types of materials, so it's essential to specify the scale being used when reporting Rockwell hardness values.

Precipitation hardening is also known as age hardening and is used to strengthen certain types of alloys, in particular those based on aluminium, magnesium, and some steels. The treatment itself is a three-step process, a combination of solution treatment (solutionising) and ageing.  During the first step the alloy is heated to a high temperature (also known as the solution treatment stage) it is generally heated to just below its melting point. This high heat allows metal atoms and alloying elements to dissolve into a solid solution. This treatment basically homogenises the alloy’s composition. Reducing any segregation of elements.The second step is quenching (rapidly cooling) to hold the alloy’s new microstructure.Before finally being heated at a lower temperature for a long-time (ageing). During the ageing process the alloying elements begin to separate from the solid solution. They form microscopic precipitates (particles) within the material structure. These precipitates hinder the movement of structural defects (dislocations) within the crystal lattice of the material. Consequently, impeding plastic deformation and improving strength and hardness.There are two stages within the ageing process, nucleation and growth. At the beginning, during nucleation, small clusters of precipitate atoms begin to form with the alloy’s matrix (nucleation). Nucleation sites can include crystal defects, grain boundaries, and other imperfections. During the “growth” stage and once nucleation has occurred, the precipitates grown in size and number. Then continue to hinder the movement of dislocations, effectively strengthening the material.

The Rockwell hardness test is based on the indentation depth caused by a diamond or a ball indenter under different loads. There are two main scales used in the Rockwell test: the Rockwell HRC scale (uses a diamond cone indenter) for harder materials and the Rockwell HRB scale (uses a ball indenter) for softer materials.

Induction Hardening – the surface layer of the metal part is heated using high-frequency induction heating, and then the part is quenched.  The localised heating and quenching result in a hardened surface, whilst retaining core properties.

This method is suitable for a wide range of materials, including metals, ceramics, and plastics. Due to its small indentation size the Vickers hardness test allows for testing on very thin materials and provides accurate results.

Carburising – the most common of the methods. The metal part is heated in an environment that is rich in carbon, which causes the carbon atoms to diffuse into the surface layer. The result is a surface layer high in carbon, which can be hardened through subsequent quenching (rapid cooling).

Hard materials resist deformation, indentation or scratches making them harder wearing, longer lasting and often easier to clean and maintain.

A thin, protective coating is applied to the aluminium part, forming a protective oxide layer. This layer creates a barrier against corrosion. There is the choice of decorative anodising and hard anodising. Hard anodising is the most durable anodising finish available on machined aluminium parts.

The Leeb hardness value is a dimensionless number, and it is usually converted to different scales to represent the hardness of the material in specific units, such as HRC (Rockwell C hardness) or HB (Brinell hardness).

The Leeb hardness test is commonly used for on-site hardness measurements, especially in large and heavy components, where other conventional hardness tests might be impractical or not feasible. However, it's important to note that the Leeb hardness test might not be as accurate as other laboratory-based hardness tests (e.g., Brinell, Rockwell, or Vickers) and might be affected by factors such as surface roughness and material homogeneity. Calibration and standardisation are critical to obtaining reliable and accurate hardness values using the Leeb hardness test method.

Also known as surface hardening. This heat treatment is used to improve the hardness and wear resistance of the metal’s surface, whilst retaining the toughness of its inner core. This method is particularly useful for components that need to withstand abrasive wear, impact, and other forms of mechanical stress. The metal’s surface layer composition is altered through diffusion.

Rockwell tends to be the most commonly used way of testing hardness, due to its speed and simplicity. It is also suitable for a wide range of materials including metals, plastics and ceramics. The Rockwell test offers several different scales (A,B,C etc.) based on different combinations of indenter types and applied loads.

So now that we know about what hardness means for your part and how you can obtain hardness whilst simultaneously retaining a part’s toughness, let’s talk about testing a part’s hardness. How you test a part’s hardness and the methods that are available.

The Vickers hardness test utilises a diamond pyramid-shaped indenter to create a small impression on the material's surface. Taking into consideration the weight of the load, the size of the indentation is measured using a microscope. The Vickers hardness number (HV) is calculated based on the indentation diagonal lengths.

Plating, coating or surface heat treatment often aim to provide the hard and/or hard-wearing surfaces required, whilst maintaining the materials’ inherent toughness.Hard anodising is available at Protolabs, our digital network, also offer heat treatment and painting, learn more here.

Quenching is a process used to rapidly cool a heated metal or alloy to enhance its mechanical characteristics. During the process the metal or alloy is heated to a high temperature to allow for changes in its atomic structure. It is then quickly cooled down, often by immersing the part into water, oil or exposing it to cool air/steam. This “quenching” locks in the changes to the structure that occurred during the heating process. The result, parts with very high hardness. To control the resulting hardness a tempering process may be used. Tempering prolongs the service life of the part, reducing brittleness.

Flame Hardening – a high-temperature flame is directed onto the surface of the metal part, followed by quenching. Similar to induction hardening this method only hardens the surface layer.

Hard anodised parts are tested for hardness using the Vickers test. On average, hard anodised aluminium 6082 can achieve values in the range of 300 to 500 HV, to put that into perspective, in its untreated state it has a hardness range of 80-95 HV. Exact hardness is entirely dependent on process parameters, such as anodising time, temperature, voltage and electrolyte composition. It’s also important to note that hardness may not be uniform across the entire material.

The hardness of a material refers to the materials ability to resist deformation, indentation or scratches. It is a measure of the materials hardness. There are several different tests used to display the hardness of materials including, Brinell (HB), Rockwell (HRC), Vickers (HV)and Leeb.

Hardness and toughness are normally inversely proportional to each other e.g. glass is hard, but it’s low toughness makes it very fragile. Plastics are often tough, but not as resistant to surface and impact damage as metals.

The Brinell hardness test is named after its inventor, Johan August Brinell. It involves applying a constant load or force to a spherical indenter made of hardened steel or carbide onto the surface of the material being tested. The indentation diameter is then measured optically. The Brinell hardness number (BHN) is calculated as the load applied divided by the surface area of the indentation.

Nitriding – Like carburising the metal part is heated in an environment, but this time rich in not just carbon, but also nitrogen. Nitrogen atoms diffuse into the surface, forming nitrides, which increases the hardness and wear resistance. Particularly effective for use on stainless steel and other alloyed steels.

The Leeb hardness test is a non-destructive and portable method used primarily for metals. It involves a spring-loaded end with a spherical or conical indenter. The end that makes contact with the material is released, and the rebound velocity is measured after striking the material's surface. The Leeb hardness value is then determined based on the ratio of the rebound velocity to the impact velocity.
