- The ceramic plates of air valves against abration, corrosion, dust, dirt, and sand.
- After more than 50-year operation of the first phase of Fengman Power Plant, the bearing of its turbine has heavy abration and aged.
- It also shows anti-tensile,slitting-resistant,abration,scrach-resistance,anti-pollution ,anti-chemical solvents and so on .
- The mechanism of hot-dipped aluminum is mainly adhesion wear,and that of complex boroned after hot-dipped aluminum is primarily abration wear with adhesion.
- The ceramic plates of air valves against abration, corrosion, dust, dirt, and sand.One dynamic plate and one stationary plate are made of extremely hard aluminum oxide .
