Wear Resistance of Aluminized Steel Plates

Abstract

Wear Resistance of Aluminized Steel Plates The results of the abrasion resistance measurements of aluminized steel strips are presented in the hereby paper. Steel strips of DX52D+AS120 grade, before and after a heat treatment at temperatures of 200-1000°C for 1 - 5760 minutes, were tested. Tests of the abrasion resistance were carried on in a specially built device: rotating disk - sample performing a plane-rotary motion, with an application of a lubricating medium. Examinations of the abrasion resistance were also performed by means of the block-on-ring tester. Estimations of a coating mass loss, roughness and thickness changes were carried on. The obtained results are illustrated by diagrams and macro- and micro-observations. Phase analysis investigations were also performed on samples selected after the abrasibility testing. The range of the heat treatment parameters - after which the Al-Si coating increased its abrasion resistance - was estimated.
