Brief Introduction of Coatings for Tungsten Carbide Indexable Inserts
1) TiN Coating ,its color is golden with function of reducing friction and providing wear-distinguish effect
2) Special structure Al2O3 Coating with sedimentary layer ,which is the best thermal barrier insuring cutting tools with out plastic-deformation under high-speed machining, dry-cutting condition.
3) TiCN coating with function of anti-abrasive wear performance ,and improve wear-resistance in the flank face significantly
4) To strengthen its cutting edge anti-shocking and wear-resistance performance by means of taking gradient sintering technology ,so as to improve its breakage resistance strength of cutting edge .
5) The carbide with special crystalline-structure ,improves the red hardness of tungsten carbide substrate and strengthen its performance when work in high temperature
