自蔓延烧结法制备 Al4 C3涂覆金刚石复合材料
Coating with Al4 C3 film on the surface of diamond by self-propagation high temperature sintering(SHS)
摘要
Abstract
Al-TiC boned diamond composites were fabricated by self-propagation high temperature sintering (SHS)from Ti/Al/Graphite/Diamond powders.The samples were analyzed by XRD,SEM with EDS.The results show that Al-TiC boned diamond composites were obtained by SHS.The main phases of the products were Al,TiC and diamond by SHS from every raw material.Meanwhile,the Al4 C3 coating was formed on the face of diamond.When Al mass fraction was higher (80%),Al4 C3 coating had a fine organization with a size of 1-5 μm.With Al mass fraction decreasing to 60%,Al4 C3 organization became coarse.Meanwhile,many bud shaped precipitates with a size of 5-20 μm formed on the coatings.But as Al mass fraction decreased to 40%, diamonds were easily broken because of its graphitization.关键词
