The Alpha Stainless Plus Drill Bit is the ultimate solution for drilling stainless steel materials and here's why.
Metal in aqueous solution, and ion-conducting electrolyte electrochemical reaction produced by the damage. In the reaction process there is current generation, corrosion of the metal surface there is a cathode and anode, the anodic reaction so that the metal loses electrons into positively charged ions into the medium, known as the anodic oxidation process. The cathodic reaction is the oxidant in the medium absorbs the electrons from the anode, known as the cathodic reduction reaction, these two reactions are independent of each other but at the same time, known as a pair of conjugate reaction. This makes the metal surface cathode and anode form a short-circuit battery, the corrosion process has current generation, such as metal in the atmosphere, seawater, soil, acid and alkali salt solutions, tap water, water for injection and other media corrosion belongs to this category.

Precision stamping die industry uses corrosion-resistant tungsten carbide block, the main corrosion electrochemical corrosion, usually using WC + cobalt + (chromium, nickel, tantalum, niobium and other carbides). This composition ratio design of tungsten carbide grades has very good electrochemical corrosion performance.

The design of tungsten carbide grades needs to be based on different types of corrosion for the composition ratio design study. Corrosion-resistant tungsten carbide used in the oil and gas industry extraction and transport equipment, the main corrosion for chemical corrosion and physical corrosion is usually used WC + Ni + (other carbides) composition. This design of tungsten carbide grades has very good chemical and physical corrosion properties.
Classification according to corrosion mechanism Metal corrosion can be classified into chemical corrosion, electrochemical corrosion and physical corrosion according to the corrosion mechanism, among which electrochemical corrosion is the most common and the most serious harm to the metal.

Physical corrosion is caused by the migration of substances, solid metal in the liquid medium dissolved and transferred to the liquid, making the metal damage, so there is no current generation, is a purely physical process.
Chemical corrosion refers to the corrosion caused by the direct chemical reaction between the metal surface and the non-electrolyte. There is no current generation during the reaction, such as when the cemented carbide is heated in air, the binder cobalt reacts chemically with oxygen in the air to generate loose cobalt oxides; The characteristic of this type of corrosion is that under certain conditions, the oxidant in the non-electrolyte directly interacts with the atoms on the surface of the metal to form corrosion products, and the transfer of electrons during the corrosion process is carried out directly between the metal and the oxidant, so there is no current generation. Metal oxidation at high temperature is generally considered to be chemical oxidation, but because high temperatures can cause the formation of semiconductor oxide skin on the surface of the metal, so there are scholars will also be high temperature oxidation into the electrochemical mechanism.
