Along with development of science and technology, the physical vapor deposition (PVD) technology also develops in succession and is applied, the physical vapor deposition (PVD) technology itself is divided into three kinds: vacuum vapor plating, vacuum sputtering plating and vacuum ion membrane plating, especially vacuum ion membrane plating, with fastest developing speed over past ten years, become one of current state-of-the-art surface treatment mode.The principle of vacuum ion membrane plating is under vacuum condition, adopt the arc-discharge technique of low voltage, big electric current, utilize geseous discharge to make target evaporation and make evaporated material and gas that ionization all take place, utilize the booster action of electric field, make to be evaporated material and reaction product is deposited on the workpiece.It mainly is decoration film coating and instrument plated film that workpiece surface is handled, and decoration film coating can improve the luminance brightness and the color and luster of workpiece surface, and the instrument plated film can improve the hardness and the wear resistance of workpiece surface.And in plated film processing, the characteristic of target also can have influence on the quality that workpiece surface is handled, thereby seeks the fine target, to promote coating effects, then becomes the focus that industry is paid close attention to.
For this reason, the spirit that the applicant is adhering to research innovation, keeping on improving is utilized its professional eye and expertise, works out a kind of suitable industry utilization, is not only applicable to target, can also can replace other metal, does the cochrome of other products such as wrist-watch.
Summary of the invention
The object of the present invention is to provide the cochrome of a kind of high-density, erosion resistance is strong, surface brightness is high platinum colour system, it has good plating performance, be applicable to physical vapor deposition, plated film obtains splendid luminance brightness and color and luster, promotes the quality that workpiece surface is handled.
For achieving the above object, the present invention adopts following technical scheme:
A kind of cochrome, this alloy is by weight: 40 ~ 85% cobalt, 10 ~ 55% chromium, surplus are trace element, and described trace element is one or more in molybdenum, nickel, iron, carbon, manganese, silicon, nitrogen, titanium, copper, aluminium, the vanadium.
Such scheme further improves: the content of described cobalt is 60 ~ 70%, the content of chromium is 25 ~ 35%, and surplus be micro-.
Such scheme further improves again: the content of described cobalt is 63%, the content of chromium is 27%, the content of molybdenum is 5.5%, the content of nickel is 2.5%, the content of iron is 1.75%, the content of carbon is 0.25%.
The metal of the platinum colour system that cochrome provided by the invention is a kind of high-density, erosion resistance is strong, surface brightness is high is not only applicable to do to electroplate target, can also can replace other metal, does other products such as wrist-watch, and alloy surface compactness is good.
The present invention is used for doing to electroplate target, make full use of its satisfactory mechanical property, physical vapor deposition adds man-hour, the alloy evaporant is difficult for oxidation, the plated film purity height that forms, compactness is good, can make workpiece surface obtain the coating of splendid luminance brightness, color and luster, hardness and wear resistance, promotes the quality that workpiece surface is handled.
