Abstract

Recent advances in the commercial exploitation of electro spark coatings have focused on improving surface roughness by depositing Ti, Mo, V, or W over an interlayer of Cu, Sn. Pb, or Cd on the top of a tool steel material. This paper presents results of a systematic pin-on-disk experimental study of different type bilayer coatings (Cu-Sn/bronze, bottom layer; Ti and Mo, top layer) deposited on a Type 45 steel. The results are discussed in terms of friction coefficients obtained under different dry·friction conditions (speeds ranging from 0.3 m/s to 0.8 m/s, and pressures ranging from 10 N to 40 N). An additional focus is on scuffling resistance of faces in friction, microhardness and surface roughness of coated items, and the competitive advantage of using advanced surface coatings.
