The use of sprayed tungsten carbide increases the service life of the screw by 5 times

       

A foreign customer, he produces a weeder, there is a screw part in it, which used to be hard chrome-plated, but after 6 months of operation (7 days a week, 24 hours a day) , The outer diameter of these screws wears up to 0.030 inches. When there is severe wear and tear, parts need to be replaced, which invisibly increases the company's operating costs.

Later, with our assistance, the screw produced by the company used sprayed tungsten carbide technology, and each screw will have a 0.01 inch sprayed tungsten carbide coating (the overall coating is 0.02 inch). After testing for 2 and a half years by working 7 days a week and 24 hours a day, the measurement was carried out and found that:



The entire screw has no wear except the tungsten carbide coating, and there is no obvious flight side corrosion. It is completely possible to re-spray the outer tungsten carbide coating and continue using it.



Compared with the previous method of chrome plating, spraying tungsten carbide increases the service life of the screw by 5 times, which greatly saves the company's expenses and reduces the problem of machine failure.
