heal.abstract	A wear resistant metal matrix composite with a hard tool steel matrix and titanium carbides (TiCs) as reinforcing particles was produced on the surface of a plain carbon steel, using the technique of plasma transferred arc alloying. An almost uniform alloyed layer free of cracks and porosities having a thickness of 0.8-1.0 mm and a hardness of 850-900 HV was achieved. The microstructure consists of a matrix of martensite and residual austenite and primary TiC (MC) carbides as reinforcing particles. Pin-on-disk tests using an alumina counterbody with applied loads in the range of 9.8-39.2 N and sliding speeds between 15 and 75 cm/s were conducted and the wear rate was found of the order of 10-s mm(3)/m. For the lowest sliding speeds of 15 and 30 cm/s the wear rate is proportional to the applied load over the whole range of loads and the dominating wear mechanism is plastic deformation. At sliding speeds of 55 and 75 cm/s the dominating wear mechanism is oxidation and a transition from mild to severe oxidational wear occurs when the applied load exceeds a value lying between 29.4 and 39.2 N. In support of the above hypotheses are the morphology of the surface and the nature of the wear debris produced. (C) 2002 Elsevier Science B.V. All rights reserved.	en
