PROPERTIES OF WC-Cu ELECTRO SPARK COATINGS SUBJECTED TO LASER MODIFICATION
Journal Title: Tribologia - Year 2017, Vol 275, Issue 5
Abstract
The article presents the possibilities of using laser surface modification on the way EDM to better tribological properties. The paper tries to expand knowledge in the fields of the application of electrospark deposition. Surface treatment by applying a coating by electrospark deposition has many advantages (e.g., local interface or applying thin layers); therefore, this technology is used in the industry. Concentrated streams of laser beams can effectively modified the state of the electrospark coating, WC-Cu, and improve its performance. The aim of the study is to evaluate the influence of laser treatment on the properties of electrospark coatings. Evaluation of the properties of the coatings after laser treatment was carried out by observation of the microstructure, surface geometry analysis, and tribological test.
