Witryna1 paź 2000 · The transfer film formation was influenced by polymer structure characteristics, tribochemical reactions and friction conditions. 1. Introduction. The application conditions of the self-lubricating polymer-matrix materials are tending to be more severe with development of new technology at present. Witryna1. Calcium build-up on the pool surface. High pH levels will cause calcium carbonate in the water to precipitate or bond to the fibreglass surface. When this happens, it often leaves a white gritty layer that looks much worse when dry. As the picture shows, this white layer becomes very noticeable when the pool water drops below its normal level.

WitrynaThe wind of AlO 2 departing from an Al-rich surface in vacuum seems to leave the surface cleaned of its usual Al 2 O 3 film, and prevents new oxygen arriving to oxidize the surface. The surface can remain clean therefore if the temperature and vacuum is good enough (Giuranno, 2006 and Molina, 2007). One would expect therefore that Ni …
