Abstract
The main goal of this work is to study dry sliding wear behavior of NiCrSiB-TiB2plasma sprayed coating against NiCrSiB coating. NiCrSiB-based powders with 10, 20, 40 wt.% TiB2particles content were deposited on steel substrates by plasma spraying. The structure of NiCrSiB-TiB2coatings consists of Ni-based matrix and TiB2and CrB grains. Among the coatings studied, the NiCrSiB-20wt.%TiB2shows excellent wear-resistance. The worn surfaces were observed using scanning electron microscopy and Auger electron spectroscopy to determine the wear mechanisms.
