耐磨环氧胶粘涂层冲蚀磨损特性的研究

本文对气固冲蚀和浆体冲蚀条件下耐磨环氧胶粘涂层的磨损特性进行了研究。结果表明,这种涂层的冲蚀磨损是由粘结剂的磨损和抗磨填料的磨损所组成;填料粒度和磨料粒度都对涂层的气固冲蚀磨损有影响,但在给定的试验条件下,填料粒度对涂层的浆体冲蚀磨损影响甚微。文章指出,耐磨环氧胶粘涂层在气固冲蚀和浆体冲蚀下的磨损机理相似,但磨损规律却有所不同;耐磨环氧胶粘涂层尤其适用于浆体冲蚀的场合,可以明显地提高机械过流部件的使用寿命。

Study on Slurry Erosion Wear Properties of the Antiwear Adhesive Coatings

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.
