涂镀是在工件表面局部快速电化沉积金属的新技术。涂镀时,把直流电源的负极接到工件上,正极与涂镀笔相连接。用棉花和40％棉、60％涤混织的套子包裹涂镀笔上的阳极,蘸上快速沉积的金属有机铬合物水溶液,与工件接触并作相对运动。溶液中的金属离子在电场作用下沉积在工件表面上。随着通过电量的增加,沉积层逐渐增厚,直至所要求的厚度,见图1。涂镀技术主要用于保护和维修金属零件,以提高零件的使用寿命和可靠性,提高设备的利用率,减少配件的生产和储运。在增产节约,修旧利废,节约能源和使生产工序合理化方
Coating is a new technology for rapid and localized electro-deposition of metal on the surface of workpieces. When coating, the DC negative power supply to the workpiece, the positive and coating pen connected. The anodes on the pen were coated with cotton and 40% cotton, 60% polyester and cotton knitted dunnage, dipped in a rapidly deposited aqueous solution of a metal-organic chrome and contacted with the workpiece for relative motion. Metal ions in the solution deposited on the workpiece surface under the action of an electric field. As the charge increases, the deposit thickens up to the required thickness, see Figure 1. Coating technology is mainly used to protect and repair metal parts, to improve the service life and reliability of parts, improve equipment utilization, reduce the production and storage of parts. Increase production and save, repair old and used waste, save energy and rationalize the production process
