热压烧结法

真空热压烧结法是最经济、高效地制备ZnS多晶的方法之一。

Vacuum hot-press is one of the effective and low-cost methods by which poly-crystalline ZnS bulk is prepared .

目前制备的方法有：搅拌铸造法、热压烧结法、粉末冶金法等，但各有其局限性，因此需要一种新的方法来更有效的制备复合材料。

At present , there are many methods of preparation composite material , such as stir-casting process , hot-press sintering , powder metallurgy and so on , but they have some limitations . Therefore , a more efficient new method for preparation of composite materials would be demanded .

采用热压烧结法得到了高致密度的复合材料.当WC／Co的体积分数达到40%时，在1900℃，35min；

The relative density of composites with addition of 40 % WC / Co that sintered at 1900 ℃ for 30 minutes under 35 MPa pressures , is up to 98 % ;

简要论述了Al2O3-SiC复相陶瓷材料的常用制备方法，如无压烧结法、热压烧结法、气压烧结法和溶胶-凝胶法等，重点介绍了碳热还原法。

The preparation methods for Al2O3-SiC composite ceramics materials are reviewed , such as pressureless sintering , hot pressure sintering , gas pressure sintering and sol-gel method , etc. , and focusing on carbon thermal reduction method .

影响热压烧结法的工艺参数有压力、温度、保温时间、磁性磨粒颗粒大小，配比等。

The hot pressing sintering process parameters : pressure , temperature , holding time , magnetic abrasive particle size and weight ratio .

此外，以Sn为添加剂，用热压原位反应烧结法可靠获得了纯度达98%以上的多晶Ti3AlC2致密块体材料。

Furthermore , using the Sn additives , the polycrystalline Ti_3AlC_2 bulk can be reliably synthesized in-situ by hot-pressing the mixtures of titanium , aluminum and graphite powders .

目前，大多数金刚石钻头采用粉末冶金热压方法烧结，热压法普遍存在烧结温度较高，对金刚石的原始强度产生不利的影响，也直接影响钻头的质量。

At present , most diamond drill bits are produced by hot-press sintering method in which sintering temperature is so high that it will damage the original strength of diamond and then lower the quality of diamond drill bit .
