The Efficacy of the Application of Highly Specialised Surface Engineering Methods in the Economy.Case Study. Jerzy Smolik1,Adam Mazurkiewicz1,Jan Walkowicz1 (1.Institute for Terotechnology, Pulaskiego 6/10, Radom 26-600, Poland) 摘要:The development of materials technologies, including surface engineering is one of the main trends in the knowledge-based economy. The direct advantages......
of 200-250 μm from the surface after HCPEB irradiation. Rapid heating and subsequent rapid solidification induce heavy plastic deformation, which results in that the laminated structure of pearlite is substituted by dispersive rounded-like cementites in the near-surface. The effect of HCPEB treatment can reach more than 500 m depth from the surface. The original crystalline structure is changed......

Also the initial efficiency of natural graphite is increased by surface modification which can reduce the first irreversible capacity loss[6]. To a great extent, the structure, the particle size......
surface area of 115.65 m2/g, nearly twenty times greater than that of bare LiFePO4. The high specific surface area is mainly attributed to porous network structure. When 20% carbon is applied, the specific surface area decreases abruptly because of the disappearance of porous network structure and the formation of smooth grains. Fig.3 Specific surface areas of samples with various carbon......
