Research of the Durability of a Covering from Oxide Ceramics
A lifetime of details directly influences the lifetime of machines and equipment. Details in most cases wear out, instead of collapsing. Raising their wear of resistance is a perspective problem. The most economic way is drawing hardwearing coverings on a surface of details made of carbon steel. In our work coverings from oxide ceramics (Al2O3 and Al2O3+TiO2), put by the way of a gas-flame spraying onto a surface of specimens made from carbon steels C20 and C45 were investigated. Before a conversion coating specimens became hardened, a temper was made, the surface was exposed to sandblasting, and the special sub layer for raising an adhesion of a covering with a basis was put on. After drawing a ceramic covering, the micro hardness of a covering and a basis was measured. Then the contact and abrasive wear resistance of surfaces on original installations was tested. The agency on wear- resistance of an aspect oxide ceramic type of wear – contact and abrasive, heating of the superficial layer arising because of a friction of two surfaces was investigated. At the end of the work, leading-outs are presented as a recommendation on the application of oxide ceramics for raising of wear resistance of steel details.
