Surface treatment material for abrasion-resistant alloy casting

Abstract

The invention discloses a surface treatment material for an abrasion-resistant alloy casting. The surface treatment material comprises, by weight, 2-5 parts of aluminum silicate, 2-5 parts of calciumbentonite, 5-11 parts of kieselguhr, 2-5 parts of quartz powder, 3-7 parts of olivine powder, 1-3 parts of alundum powder, 11-14 parts of dextrin powder, 2-5 parts of aluminum sulfate powder, 11-13 parts of polyvinyl alcohol, 14-16 parts of ferric oxide powder, 7-9 parts of n-caprylic alcohol, 6-8 parts of nano attapulgite, 5-11 parts of grass ash and 2-5 parts of sodium orthophosphate. By adoption of the surface treatment material, the abrasion resistance and corrosion resistance of the surface of the casting are effectively improved. In addition, the alloy strengthening process of the surface of the casting can be completed at a time at the same time of casting, so that the technique is simplified, the abrasion resistance of a strengthened layer is about 2-3 times that of a base material, and the acid corrosion resistance of the strengthened layer is about 5 times that of the base material.

Description

technical field [0001] The invention belongs to the field of surface treatment, in particular to a surface treatment material for wear-resistant alloy castings. Background technique [0002] Castings are closely related to daily life, especially in agricultural machinery. The operating devices of agricultural machinery often come into direct contact with sandy soil during the working process, and the sandy soil often contains hard particles of stones and sand. The operating devices of agricultural machinery are in service in such an environment and are subject to strong abrasive wear. When the pH of the soil is strong, the corrosion on the surface of the operating device of agricultural machinery is also very serious, and it will also induce corrosion-wear joint action, shortening the life of the agricultural machinery. The service life of working equipment. The erosion, corrosion, wear, corrosion, and the interaction between wear and corrosion on the surface of agricultur...

Problems solved by technology

This leads to the complexity of the manufacturing process of agricultural machinery. In addition, it is inconvenient to guarantee the secondary strengthening process of some large agricultural machinery.

In addition, there is also a method of coating the surface of agricultural machinery with paint to improve the surface wear resistance of agricultural machinery. However, due to the limitation of the wear resistance of the paint, the effect of this method is not satisfactory.
