Hard Anodizing for Aluminion Pieces - Supporting Friction and Wearing-For The Automotion And Motorcycling Industry

摘要

Aluminium pieces are being used more and more in the automotion industry. But they have to support great wearing due to the reaction to some chemical product (oils, gasolines, gasoil, etc). Pieces also suffer an important wearing due to friction and pressing work. The hard anodizing type II is used and it is observed that with the new aluminium and magnesium alloys (which are not going to be discussed now), together with sealing polymers and silanos a higher resistance against use and wearing is reached. Therefore, chains formation in the silanes interfase were studied. It was observed the reaction mechanism formed in between the aluminium-metal and the oxide resulting from hard anodizing. The interfase occurring with silane and silane oxide are free radicals of silicon and oxide silicon, respectively, which for the polymer This paper analyzes and try to explain the polymers application in pumps for injecting oil and brake liquide.
