Surface impregnation by particle injection: laser impregnation
Luleå tekniska universitet.
1988 (English)In: Optics and Laser Technology, ISSN 0030-3992, E-ISSN 1879-2545, Vol. 20, no 1, p. 33-35Article in journal (Refereed) Published
Abstract [en]

Wear resistance can be improved by laser impregnation - the surface layer of a base material is melted and hard wear resistant carbide particles are injected into the melted pool. Previously, experiments were mainly performed in a vacuum chamber at a laser power of 10 kW. In this paper, results are presented of experiments carried out with 1.5 and 2.5 kW lasers at ambient atmospheric pressure. Laser impregnated layers show increased wear resistance of the order of 20-40 times for impregnated compared to untreated aluminium, and 5-20 times for impregnated compared to hardened carbon steels
