A Research on Solid Aluminizing New Technique

You Xiangqun; Xi Liqing  
ake alumina with charcoal powder in the ratio of 2 to 1 as an interstitial agent, where 10% of aluminium powder is used as the feeding media, and 3% of ammonium chloride as catalytic agent. This new solid aluminizing technique can lower the content of the aluminium powder to 10%. The new process can not only present both thick and homogeneous aluminized layers on the iron and steel surface, but also leave catalytic agent porous enough after use, with a smoothly finished surface remaining on the test sample. There exists no problem about the binding or sticking commonly left by traditional solid aluminizing process. The aluminized elements have strong resistance to oxidation at high temperature, and can also resist heavy corroding with its ability being extremely higher than that in the element unaluminized. The aluminized pieces can be compared with those of stainless steels.
