The present investigation compares blast erosion characteristics of coatings that are prepared with abrasion resistant surface treatment materials and various consolidation processes. Furthermore, it elucidates operating mechanisms in blast erosion of various sprayed coatings. The investigation presents the blast erosion test conditions and assessment of test results and discusses the effects of coating materials on abrasion loss and impingement angle on abrasion loss. It includes illustrations on SEM observation and cross-sectional observation of damaged areas. In addition, information on blast erosion resistant characteristics of materials tested and wear mechanism in blast erosion is also provided.
