7 for the divided tool s profile. In order to further study the wear mechanism of sialon ceramic tools the selected inserts mentioned above were split and polished along the central axis and at 1 2 depth of cut so as to obtain the corresponding wear interface. 8 3 friction and wear behavior of sic ceramics sintered with a small amount of yttria additive 189. There are two types of situation where abrasive wear may occur.

Abrasive wear wear by abrasion is the most frequently encountered wear mechanism in industry. Abrasive wear occurs when a harder material is rubbing against a softer material. When one considers the intimate contact of two sliding surfaces where hard particles are either present or formed during sliding abrasive wear can occur as a consequence of both plastic deformation and fracture mechanisms. 8 5 wear mechanisms 191.

However cutting performance wear mechanism and interfacial stability of tib 2 based ceramic cutting tools in high speed cutting of titanium alloys was unclear. Wear is a progressive damage of a surface in contact with another one. What is abrasive wear. Metal ceramic polymer can suffer from wear damage.

We shall mainly discuss wear of metallic materials although all solid material e g. The wear affects the potential life of the prosthesis and subsequent removals of in vivo implants. Such damage results in the formation of fragments or debris that leave the tribological system wear may cause direct failure may reduce tolerances and surface finish or induce a surface damage that is responsible for the subsequent failure of the component most often by fatigue. Goswami t.

8 sliding wear of sic ceramics 187. Sliding wear of ceramics 185. 8 4 influence of mechanical properties on sliding wear of sic ceramics 191. However in polycrystalline ceramics the amount of plastic deformation that can occur is strictly.

If there are only two rubbing parts involved in the friction process the wear is called two body wear. The mechanisms of wear.
