Abstract: Sintered Silicon Carbide material with fine grain structure shows excellent wear resistance, highly chemically resistance, excellent performance in a wide range of applications. This material can improve upon the exceptional corrosion and erosion resisting properties through the addition of unique micro pores. A designed spherical-pore Silicon Carbide material was obtained after pressureless sintering. The photomicrograph shows a typical appearance of unique micro pore. SEM was also employed to investigate the micro-structure of as-prepared SiC material. The properties of micro-pore Silicon Carbide, such as density, hardness, strength, etc. were determined in detail. The relationship between the spherical-pore structure and properties of Silicon Carbide were discussed.

Abstract: This paper developed a new type of ball-type porous metal preparation method. A brief introduction of this new type of spherical aluminum-based metal forming method of porous, pore structure and its compression and energy absorption properties, but also involves the performance of spherical holes iron foam.

Abstract: This paper reveals a preparation method of a new type of porous metal. Because of the high cost and low quality, the actual large-scale application of porous metal is not very widespread. The new manufacturing methods proposed by paper will enhance the practical application of porous metals. The hollow part of hollow metal balls can be used as the main body of porous metal to manufacture porous metal. First, a hemispherical-thin layer metal structure was obtained by plastic processing from a metal plate. Then, this metal structure was connected appropriately according to the body-centered cubic structure to from a new type of spherical porous metal. The method is simple, high productivity, easy control and low cost.
