In this paper, the effect of titanization temperature and titanization time and differentkinds of materials on the thickness of titanized layer has been studied. The composition andstructure of titanized layer have been analysed. The result of the experiment shows that thetitanized layer has the properties of ultrahigh hardness, excellent wearability andacid-resistant ability. This technology is applied to tools and dies, the application life ofwhich has been greatly increased. This technology has the advantages of the least inve...
