金属板术和相关成品

[中文适用范围]： 电镀是一种在物体上涂上一层或多层相对较薄、紧密粘附的一种或多种金属层的过程。它是通过将待涂覆的物体放置在电镀架或固定装置上，或者篮子中或旋转容器中，以使得合适的电流可以流过它，然后将其浸入一系列溶液中来完成的。按计划顺序冲洗。电镀所获得的优势可能是相当大的；一般来说，当需要赋予基础材料（出于成本、材料保护和物理性能原因而选择）其不具备的表面性能时，使用该工艺。应该指出的是，虽然电镀是最广泛使用的将金属施加到基材上的工艺，但它们也可以通过喷涂、真空沉积、熔覆、热浸镀、化学还原、机械电镀等来施加。 应用电镀的目的用于各种应用的金属如下。 [外文原描述]： Electroplating is a process whereby an object is coated with one or more relatively thin, tightly adherent layers of one or more metals. It is accomplished by placing the object to be coated on a plating rack or a fixture, or in a basket or in a rotating container in such a manner that a suitable current may flow through it, and then immersing it in a series of solutions and rinses in planned sequence. The advantage to be gained by electroplating may be considerable; broadly speaking, the process is used when it is desired to endow the basis material (selected for cost, material conservation, and physical property reasons) with surface properties it does not possess.It should be noted that although electroplating is the most widely used process for applying metals to a substrate, they may also be applied by spraying, vacuum deposition, cladding, hot dipping, chemical reduction, mechanical plating, etc. The purpose for applying an electroplate and the metals used for various applications follow.Cross Reference: ASTMA164,ASTMA165,ASTMB177,ASTMB200,ASTMB253,ASTMB254,ASTMB456,ASTMB488,ASTMB503,ASTMB545,J207,J207_201205
