Özet

Purpose: This study aims to investigate the potentiality of brush chromium plating process to replace conventional hard chromium plating.Design/methodology/approach: In this study brush chromium plating was applied over a H13 quality tool steel. Electron microscopy examinations and X-ray diffraction analysis were conducted in order to reveal the structural features of the coatings. Mechanical properties of the coatings were determined by hardness measurements and wear tests. Wear tests were conducted at room temperature and 500°C.Findings: Brush chromium plating, which is an environmental friendly alternative for conventional chromium plating, has potentiality to enhance wear resistance of steels.Research limitations/implications: Brush chromium plating process has good potential to replace hexavalent chromium. Further studies should focus on effect of electro-chemical parameters on structural properties of trivalent based hard chromium deposit by brush plating process.Originality/value: There have been significant researches on replacement of hexavalent based hard chromium plating in literature. Replacement by brush plating process with trivalent chromium containing electrolyte has been scarcely investigated especially for utilization in wear related applications at elevated temperatures.
