摘要： PURPOSE: To assure mechanical strength and to improve bending workability by forming structures which are connected and bonded to each other by bridging parts consisting of hypereutectic structures. CONSTITUTION: Gaps 3 are formed among the particles of base powder 1. These gaps 3 are communicated with each other to form infinitely curving open cells. The particles of the base powder 1 are positively connected and integrated to each other by the bridging parts 2. The bridging parts 2 are interposed between the particles of the base powder 1 in such a manner without bonding these particles by direct contact. The base powder 1 is composed of Al or its alloy. The bridging parts 2 contain an eutectic element having the m. p. higher than the m. p. of the Al and making eutectic reaction with the Al above the eutectic point and consists of the balance substantially Al and in addition, their structures are composed of the hypereutectic structures. As a result, the porous aluminum sintered material adequate for sound absorbing materials, filter materials, adsorbent materials, etc., for industrial apparatus, such as high- speed electric trains and automobiles, is provided.

摘要： PURPOSE:To provide the overlay alloy for a slide bearing to fully show the wear resistance and the fatigue resistance even under the condition of high temperature where the temperature of the lubrication oil rises. CONSTITUTION:Electro-plating is realized on a bearing alloy 2 where thin plating 3 of nickel is made by using lead, tin or a plating bath containing lead, tin, and copper, to form the alloy overlay of Pb-Sn or Pb-Sn-Cu. In addition, after the silver plating is made by the electro-plating from the silver cyanide bath is realized, and the bearing is heated to 120-220 deg.C to diffuse the silver into the overlay layer to form a novel overlay alloy 4 having a composition consisting of, by weight, 0.1-5% silver, 2-12% tin, and/or 0.1-5% copper, and the balance substantially lead. The slide bearing having this overlay alloy layer 4 is excellent for the wear resistance and the fatigue resistance at high temperature, and extremely useful as the sliding element.
