Structure and properties of nitride coatings deposited from filtered vacuum arc plasma generated by evaporation of cromium-aluminum powder cathode
Keywords:
vacuum-arc deposition, powder cathode, filtered plasma, nitride coatings, hardnessAbstract
CrAlN coatings were synthesized by filtered vacuum-arc deposition method using the powder Cr0.5Al0.5 cathode. High hardness (30-36) GPa, low roughness of (40-50) nm, low friction coefficient and high wear durability enable use of these coatings as protective ones. The cathode material was made by hot compaction of chromium and aluminum powder mixtures, its structure and phase composition have been investigated. Hot compacted cathode blank have a structure of aluminum matrix composite of minimal (3-4 %) porosity, whose strength and plasticity is apt to be machined for fabrication the cathode.
