虽然功能梯度硬质合金已开发多年 ,但是对其了解几年前还是一无所知。最近芬兰技术大学ＭｉｃｈａｅｌＧａｓｉｋ教授在一篇题为“功能梯度ＷＣ/Ｃｏ材料的成型和烧结的文章中就烧结梯度硬质合金采用新的方程组对成型进行了研究 ,他认为影响梯度组成和结构的因素主要包括粉粒的 Although functionally graded cemented carbides have been developed for many years, they still know nothing about it a few years ago. Recently Professor Michael Gasker of the Finnish Technical University, in a paper entitled "Forming and sintering of functionally graded WC / Co materials, investigated the shaping of sintered gradient cemented carbides with a new set of equations that he considered influencing the composition and structure of the gradient The main factors include the powder
