i Technical information PVD COATINGS USED FOR TOOLS AT COATING Coating AlTiN Structure Gradient Hardness 3700 HV0,05 Max. working temp. 900°C Coefficient of friction 0,3 Purplish-Grey Color of coating The AT Coating, with the increased Aluminum (Al) content, features high hardness and temperature resistance. The released from the coating, during processing, aluminum oxides serve as additional lubrication of a tool, and at the same they create a thermal barrier, preventing the coating from being worn out, even in the most extreme conditions. Chemical composition and the nanogradient structure ensure high hardness of the coating. As a result, the high resistance to abrasion is achieved, which directly translates into the tool’s longer life. The coating may be used for tools exposed to high temperatures, and is suitable for work both, with coolant and without it. The coating is designed for processing materials from the Groups P, M, K, N, S. TIB2 COATING Coating TiB2 Structure Monolayer Hardness 4000 HV0,05 Max. working temp. 900°C Silver Współczynnik tarcia 0,35 Color of coating The material of coating, the TB (titanium diboride), is a ceramic material with outstanding properties with regard to its hardness and resistance to abrasion. With its carefully prepared composition (no affinity with aluminum), the material provides high chemical stability and prevents the processed material buildup on cutting edges. The dropless method of manufacturing the coating allows to obtain a very smooth finish, which in turn translates into a very good quality the workpieces’ surfaces. The coating is designed for processing materials form the Group N, mainly aluminum alloys (Si<12%) and unalloyed titanium. 12 282
