HSS circular saw blades are coated with PVD coating method using different alloying elements on the cutting surface in order to improve their technical characteristics and to improve their performance. PVD (physical vapor deposition) Production of PVD partially ionized metal vapor, it is a method of forming metal-based hard coatings by reacting with certain gases and forming a thin film having a certain composition on the saw. The process is carried out under high vacuum conditions. The process effects in 250-450℃. Coating thickness varies between 2-5 µm. The advantages of pvd coating for hss circular saw are as follows:
High hardness
Long lifetime
Thin film thickness
Chemical stability (acid and corrosion protection)
Low friction coefficient
Edge sharpness protection
Lack of hardness loss
Homogenous coating
High quality
Reasonable price and short delivery time
