Effects of laser surface texturing on the wear and failure mechanism of grey cast iron reciprocating against steel under starved lubrication conditions

Purpose – The purpose of this paper is to investigate and discuss the effect of multi-shape laser surface texturing (LST) steel surfaces on tribological performance. Design/methodology/approach – The textured surface with some specific formula arrays was fabricated by laser ablation process by combining patterns of circles and triangles, circles and squares and circles and ellipses. The tribological test was performed by a flat-on-flat tribometer under dry and lubrication conditions, and results were compared with that of untextured surface. Findings – The results showed that the textured surface had better friction coefficient performance than the untextured surface due to hydrodynamic lubrication effect. Through an increase in sliding speed, the beneficial effect of LST performance was achieved under dry and lubrication conditions. Originality/value – This paper develops multi-shape LST steel surfaces for improving the friction and wear performance under dry and lubrication conditions.

Der Beitrag beschreibt, wie Verbundkreissägeblätter mit geklebten keramischen Zähnen hergestellt wurden. Dafür wurden die Keramiken, aufbauend auf bisherigen eigenen Untersuchungen, mittels Laseroberflächenstrukturierung vorbehandelt und mit einem modifizierten Lötautomaten verklebt. Anschließend wurden die Werkzeuge geschliffen und in einem Modellversuch auf ihre Funktionsfähigkeit und Einsatzverhalten untersucht.   This article presents the manufacturing of adhesively bonded circular saw blades with ceramic teeth. Based on own previous investigations, the ceramic surfaces were treated by laser surface texturing and adhesively bonded by a modified brazing machine. Then the tools were grinded and functioning and behavior were validated in a model experiment.
