- Abstract
In this study, changes of mechanical properties of low carbon steel, which widely used in steel structure, were studied after coating by Wear Resistant High-Chromium White Cast Iron (HCWI). The coating process were carried out by semi-automatic welding method using powder materials with particle size of 0.7, 0.6 and 0.5 mm. The coating materials were prepared by casting small pieces of HCWI and machining into chips, then hand crushing the chips and sieving them according to appropriate sizes. Before the welding process, the coating material was glued on the steel surface with size of 0.3, 1.0 and 1.5 mm thickness.
Electrical current for welding was selected in three modes, namely 80, 100 and 120 A.
Changes in mechanical properties after coating were evaluated by surface hardness measurement and abrasive wear testing. Analyzing chemical composition of the coating performed with relation to surface hardness. The hardest and most wear resistant layer is formed when the chromium content was around 2.4-2.6%.
