NEW CERMET ANTIFRICTION MATERIALS FOR RUBBING PARTS,
Abstract
The wear and antifriction properties of sintered metal materials consisting of matrices of low-carbon steel, stainless steel 1Kh18N9T, bronze, and nickel, unsaturated and vacuum saturated with teflon, were investigated on friction apparatus MT-7 at a load of 20 kg/sq cm and 0.03 m/sec. It was found that the wear of low carbon steel and nickel-based materials was very high, while bronze and stainless steel materials gave similar wear and friction results with teflon saturated matrices giving vastly improved characteristics: bronze-wear - 0.0001-1.0035 gm/hr, coefficient of friction 0.01-0.05 for teflon saturated vs 0.18-0.22 and 0.28-0.32 for unsaturated; steel--6 x 10-5-0.08 and 0.01-0.09 saturated vs 0.09-0.22 and 0.22 unsaturated. Bearing tests conducted in 30 and 60% nitric acid and in 1% caustic soda solution showed that saturated 1Kh18N9T material on chrome-plated 1Kh18N9T surface and saturated bronze on 1Kh18N9T gave best results respectively. End seals operating in 30% nitric acid showed least wear and friction when made of saturated 1Kh18N9T material rubbing against a chrome surface. (Author)
