WEAR RESISTANCE OF METAL DEPOSITED WITH POWDERED WIRES OF THE FE – C – Si – Mn – Ni – Mo – W – V AND Fe – C – Si – Mn – Cr – Ni – Mo – V SYSTEMS
Abstract
The development of new materials and the use of innovative restoration technologies that significantly increase the wear resistance of products are urgent tasks of mechanical engineering. Methods are being developed and special materials for surfacing are being manufactured. The most widely used surfacing wires for abrasive-wearing products are low-carbon, low-alloy, austenitic high-manganese type C, and high-speed steels type F according to the MIS classification. Widely used are surfacing carbide alloys of type P, which are composite materials and consist of reinforcing particles of tungsten carbides and a matrix. They are distinguished by the highest wear resistance under abrasive wear. A characteristic feature of the wear process of such alloys is the gradual wear of individual elements of the composition. In this case, the so-called shadow effect is observed, when more wear-resistant reinforcing particles take on the main load from destructive forces, thereby protecting the alloy matrix from wear. Thus, with equal wear resistance of the matrix, the performance of composite alloys is determined by their chemical composition, concentration, wear resistance and strength of reinforcing particles. However, the wear resistance of the matrix can also be a determining indicator when working under abrasive wear conditions.
