摘要: Abstract The relationship between dry sliding reciprocating wear, subsurface deformation and microcrack formation in Ti–35Nb–8Zr–5Ta–O( x ) has been investigated. Three zones: a chemically altered tribo-layer, plastic shear zone, zone layer were identified, their depth increasing with contact stress. Transmission electron microscopy showed {110} {112} planar slip throughout the zones, band spacing decreasing distance to wear surface. Within {110}/{110} {110}/{112} intersections observed, number density from These bands associated localized displacement, magnitude of displacement oxygen. Finally as tribo-layer was approached at intersecting observed. Microcrack propagation proceeded along interface linkage being observed reorientation occurred. Ultimately featureless surface containing cracks running both parallel perpendicular encountered. observations are consistent model for debris that involves formation, ultimately type II delamination.
