问:涂层的厚度是多少? 答:PVD的表面涂层厚度是2～5μ或约0.0001～0.0002英寸(1μ=0.00004英寸)。根据实际应用需要,可以厚些或薄些。CVD的涂层厚度是0.0003英寸(5～10μ)。问:涂层后刀具尺寸有变化吗? 答:PVD法,尺寸变化仅仅有0.0001英寸或不到0.0001英寸;此外,低温处理不会引起母材任何收缩。CVD法,尺寸有变化,可到当地涂层中心检测。问:涂层工艺的温度如何?
Q: What is the thickness of the coating? A: The PVD coating thickness is 2 to 5μ or about 0.0001 to 0.0002 inches (1μ = 0.00004 inches). According to the actual application needs, can be thicker or thinner. The thickness of the CVD coating is 0.0003 inches (5 to 10 μ). Q: Does the tool size change after coating? A: The PVD method has a dimensional change of only 0.0001 in. Or less than 0.0001 in. In addition, the low temperature treatment does not cause any shrinkage of the base metal. CVD method, the size changes, can be detected at the local coating center. Q: What is the temperature of the coating process?
