Purpose: The aim of the work is presents the influence of casting method and anodic treatment parameters on properties, thickness and structure of an anodic layer formed on aluminium casting alloys. Design/methodology/approach: Investigations were carried out on the laser profile measurement gauge MicroProf from company FRT, abrasive wear test was made with using ABR-8251 equipment delivered by TCD...
Purpose: Purpose consideration of role of phosphorus in iron alloys surface engineering and relations of the iron phosphides layers growth parameters in processes of phosphorising, phosphorcarburising, and phosphonitriding with their structure and properties. Design/methodology/approach: The layers were generated on a base of Armco iron and 0.4%C, 1.1% Cr steel as a result of annealing in a mixture...
Purpose: The paper gives a comparison of various techniques of laser surface hardening for various kinds of structural and tool steels, and special maraging steel and hardening of nodular graphite and gray cast irons. Design/methodology/approach: Experimental investigations of laser surface transformation hardening, laser remelting and laser shock processing were performed. Trials of laser hardening...
