Background
It is well known that most metallic materials react with our surrounding media in a variety of chemical reactions and adversely affect or even completely destroy the tools we have manufactured. This is a huge loss for us. According to statistics of developed countries, the loss caused by abrasion and corrosion of bare steel products accounts for about 10% of the total output of the steel products every year, and the loss amount accounts for 2-4% of national economy. Not to mention accidents, shutdowns, production stoppages, etc. caused by damaged steel and corrosion. In order to reduce the occurrence of the supersonic flame spraying method, spraying materials are attached to a workpiece, so that damage and loss are reduced. However, the supersonic flame spraying still has the large gaps of the coating sprayed on the workpiece to erode the matrix and the coating is easy to peel off and damage due to thermal expansion and contraction. This problem can therefore be solved by using the induction remelting technique. The workpiece then needs to go through these two steps to reach the specified standard. However, in the present day, the two processes are separately processed, which not only takes time and occupies land, but also has high cost and low efficiency. Therefore, an apparatus is required to complete these two processes at one time.
