Arc spraying cross head

Arc spraying cross head

The cross head sliding shoe is a new technology of arc spraying, and it is an experimental research project of the company. Application of arc spraying technology, the alloy material is sprayed directly onto the surface of the cross head of the compressor to form a combination of high strength and wear resistance of the alloy coating, the application of this new technology is the first in the country. Its features: A. to improve efficiency. The efficiency of 8-10 times higher than that of traditional hang up process. Reduce the cost of b.. The original hanging process of Babbitt coating thickness of about 10mm, leaving only the processed 3mm; spraying coating procedure only about 3mm, after processing 1.5mm, save raw materials and reduce the processing time of 50%. C. coating and high binding force. The original hanging Babbitt alloy coating process often have a bubble or slag defects, the new coating process will not produce the defect; and due to the coating surface layer, substrate surface and hung at the bottom and improve the binding force between the coating and the substrate. D. high wear resistance. By arc spraying, formed at high temperatures in Babbitt metal tin, copper and antimony compound uniform distribution on the surface of the coating, and invisible to the naked eye pinhole, improve the crosshead slide shoe wear resistance and lubricity, thereby enhancing the service life of the crosshead. This results in 2006 have been applied for national invention patent.
