【Abstract】 The device of erosion simulation experiment has been designed. The erosion simulation experiment is engaged in. The erosion resistance of chromium, Ta 10W and chromium coatings laser surface modified are investigated. The result of erosion experiment is discussed. Chromium coating is destroyed in form of removed. The adhesion between chromium coating and steel has been enhanced by means of laser surface modifying. Chromium coating laser surface modified has not peeled off in erosion. The erosion resistant of Ta 10W is the best among the three types of coating.更多还原
