Abstract

Two sets of experiments, cylinder-on-plate reciprocating wear tests and milling tests, were carried out to evaluate the performance of CrN coating layers on ferrous metals. Micro-hardness, adhesion and phases within the coating layers were also studied. The results were compared with uncoated and TiN-coated WC specimens. The experimental results show that the CrN-coated WC specimens exhibited good wear performance on wear testing, but performed poorly on milling, even poorer than the uncoated material. The main difference between these two sets of experimental results was due to the chemical affinity of Cr for Fe and the difference in the forces acting in the tests. There is detailed discussion in the report, and a fracture mechanism for the CrN-coated tungsten carbide (WC) insert in the milling of ferrous metal is proposed.
