What isPVD coatingused for

PVD stands for Physical Vapor Deposition. It is a thin-film coating process. This is a process applied in a vacuum chamber to deposit thin-film coatings on component surfaces.

A multi start thread makes a nut for example travel more per revolution than a single start thread. But I have trouble understanding or visualizing this.

In general, PVD coatings are thin film and are in the range of 1 to 5 microns. For reference, 25 microns equals 0.001 inches. Red blood cells are around 8 microns in diameter, while human hair is around 80 microns in diameter. Thus, PVD coatings are extremely thin-film coatings with thickness specification defined within this 1 to 5-micron range depending on the application requirement.

PVD coatings have a hardness value around 1500 – 4500 HV (Vickers) depending on the type of coating offered. Vickers (HV) is a microhardness unit for measuring thin film coatings. For reference, 900 HV corresponds to 67 HRC (Rockwell C) hardness. Generally, carbon steels have a hardness range around 250 HV (25 HRC), nitrided or nickel and chrome plated steels fall in the range of 600 HV to 1000 HV surface hardness. Thus, PVD coatings are extremely hard and hence, very durable and wear resistant.

PVD coating is carried out in a vacuum chamber at an extremely low-pressure range (typically 10-3 to 10-9 Torr. Standard atmospheric pressure is 760 Torr) where in the component to be coated is placed in front of a high purity target source in a plasma environment (ionized gas). A target is the primary material source used for the coating (for example: Titanium for Titanium Nitride, Chromium for Chromium Nitride, etc.) This process involves three critical steps:
