Abstract: The wear properties of antiwear adhesive coatings under solid particle erosion and slurry erosion condition were studied in this paper. The results shown that the slurry erosion wear of adhesive coating is composed of adhesive wear and antiwear filler wear. The sizes of filler and abrasive have influence on the solid particle erosion of coating under the given condition ,the size of filler be of weak influence on the slurry erosion. The wear mechanisms of antiwear adhesive coatings are similar under solid particle erosion and slurry erosion, but there is difference in the law of wear. Antiwear adhesive coating is suited to slurry erosion situation especially and can obviously prolong the service life of mechanical part.
