The influence of the machining regime was experimentally investigated on output indexes diamond grinding ceramic balls from silicon carbide, such as rate material removal and changing (decreasing or increasing) deviation sphericity ball's surface.To distinguish a particle these caused by actual applied method graphical approximation time-varying diameter sphericity.The separated particles process can vary both growing decreasing depending values parameters regime, as: discrete feeding wheel...
Abstract This paper presents the results of tests performed during grinding process ceramic materials: – polycrystalline ceramics (Zirconium ZrO 2 ) and mono-crystalline (sapphire α-Al O 3 by diamond tools. Studies have shown that concentration (thickening) tool composite changes tool's pore structure when using suitable wetted adamantine additives. Such modified has positive impact on tribological properties subsurface layer machined components. is manifested reduction surface roughness...
In the article are shown results of tests on friction and wear behavior couples sapphire against or tetragonal dioxide zirconium. Tribological characteristics zirconium (Y,Ce,Hf)-TZP in pair with a counter body from essentially better than couple sapphire/sapphire (friction force lower 1,3 times, linear 1,5 times).
Total hip replacement due to its effectiveness is the most common treatment for patients with severe diseases of joints. The modern idea choice materials (and methods their application as a pair friction) large joints are described, set scope problems and possible solutions. We characterize some directions improvement artificial human It was emphasized that so far there no perfect friction in artificial joints, it determines surgeon, taking into account anatomical physiological state...
