Wear Behaviour of Hard Cr Coatings for Cold Forming Tools Under Dry Sliding Conditions
Journal Title: Tribology in Industry - Year 2012, Vol 34, Issue 1
Abstract
Cr hard coatings are largely used in industry in metal cutting and cold forming processes; This work on quantitative way represents improvement, in terms of wear resistance, which is obtained by depositing Cr hard coating on foundation material. Wear testing is done on tribometer with block –on –disc contact geometry at sliding contact of Cr hard coated sample with steel disc. Testing was performed in conditions without lubrication at variable value of contact parameters (normal load, sliding speed). Cr hard coatings in all contact conditions show smaller values of wear rate.
