刀具在500℃下涂敷钛合金一般采用气相沉积法对刀具涂敷钛合金,需要1000～1200℃的高温,从而带来不少技术问题——退火、变形、化学成份变化等。日本住友电气公司最近研究了一种叫做“金 A 法”(Gold Ace Process)的涂敷工艺,可在500℃的温度下对高速钢或硬质合金刀具均匀地涂敷钛合金,涂层厚度为2～6微米,视具体应用而定。试验表明,硬质合金刀具经涂敷后,
Tool coated titanium alloy at 500 ℃ Generally, the titanium alloy is coated on the tool by the vapor deposition method, requiring high temperature of 1000-1200 ℃, which brings about many technical problems - annealing, deformation, chemical composition change and so on. Sumitomo Electric recently researched a coating process called the “Gold Ace Process,” which produces a uniform coating of high-speed steel or carbide tools at 500 ° C. The coating thickness 2 to 6 microns, depending on the specific application. Experiments show that after the cemented carbide tool is coated,
