摘要
长度达2～4米的活塞杆可以在同一镀槽内以调头镀的方法镀覆双层铬(乳白铬+硬铬),活塞杆的中间段无缺陷,结合力良好.办法是控制镀液量或将工件下沉.
Piston rods of 2-3 meters long can be electrophted with double-layer (crack-free and hard) chromium coatings in the same bath by turning round the rods if the solution level or the immersed section of the rod is well controlled. Adhesive strength of the coatings on the middle section surface of the rod is good and no defects in the film are found.
