Strengthening coating for aluminium alloys “astrim”, based on techology of microcircular oxidizing. Investigations of physical and mechanical characteristics

, ,

Abstract:

Complex of the physical and mechanical properties, of the physical and chemical, electro- physical and structure investigations of the material «ASTRIM» samples based on aluminium alloys B95T1 with coatings by different technological, micro-circular oxidizing methods has been taken. It was shown the coatings of «ASTRIM» is wear proof up to 250 revolution per minutes and specific pressure from 6,9 to 11,6 kg/s2. On tough surface plots a micro hardness is able to reach the values 3801 kg/mm2. Above coatings decrease the strength and fluidity limit of B95T1 alloys by tension very little but on plasticity an influence is very strong (more then 50%).
