▎ 摘　　要

NOVELTY - The bearing has a porous throttle layer (5) that is fixedly connected to the inner wall of a stainless steel base material (1). The formula of the porous throttle layer is provided with tin powder, nickel powder, phosphor bronze powder, composite graphene powder, molybdenum disulfide powder and copper powder. The mass percentage content of each component of the porous throttling layer is 10-15% tin powder, 20-35% nickel powder, 0.5-1.0% phosphor bronze powder, 0.1-10% composite Graphene powder and 0.1-0.3% molybdenum disulfide powder, the balance is copper powder. USE - Porous static pressure air bearing. ADVANTAGE - The method is configured to improve the formulation component of the porous throttling layer, each component in the porous throttle layer is combined into a whole, avoiding generation of debris blocking porous throttle layer in the processing process, and the inorganic filler is blown out by high pressure air in the using process, the throttles layer and the stainless steel substrate are firmly combined, the air flow is prevented from flowing out from the combining surface when ventilating. The method is configured to perform chromium-removing treatment on the substrate in the process, so as to improve the yield of the sintering. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of porous static pressure air bearing. DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of the stainless steel base material.
