最近,日本某公司开发了只需5min就可迅速烧结碳化钨等各种超硬合金粉粒体的高速烧结装置。该装置是将金属粉粒体装填在两个电极之间,使用独立的电源,在电流流过电极的同时,应用特殊的油压装置,对电极施加机械压力,以进行烧结加工。因是将高密度放电能量直按照射到超硬合金粉粒体的内部进行烧结,故即使不在高真空及还原条件下,也可简单地进行烧结,得到均匀、高质量的制品。因能在短时间内迅速烧结,故可抑制晶体
Recently, a company in Japan developed a high-speed sintering apparatus that can rapidly sinter various cemented carbide powders such as tungsten carbide in 5 minutes. The device is the metal powder body filled between the two electrodes, using a separate power supply, the current flow through the electrode at the same time, the application of special hydraulic devices, apply mechanical pressure on the electrode for sintering. Because the high-density discharge energy is directly irradiated to the inside of the cemented carbide powder body to sinter, it can be simply sintered without high vacuum and reduction conditions to obtain a uniform and high-quality product. Because it can be quickly sintered in a short time, it can inhibit the crystal
