Abstract
The invention discloses a kind of surface of golf club head composite film coating and film plating process.The glof club head integral surface has the coat of metal that can put forward hardness, and can be as the transition zone between the high-hardness inorganic nitride layer and glof club head of following process.After mixing high-hardness inorganic thing micron granularity particle in the coat of metal, the hardness of the coat of metal is can further improve, while the coat of metal there can be matte effect.Also there is high-hardness inorganic nitride layer on the striking surface and bottom metal coating of the glof club head, can significantly lift the hardness of golf clubs head batting surface and bottom, its damaged and abrasion is declined to a great extent.
Description
Technical field
The present invention relates to the plated film field in surface treatment, more particularly to a kind of surface of golf club head composite film coating and
Film plating process.
Background technology
Glof club head, general material are metal.Club head sole and striking surface in use, with friction
Abrasion and Light deformation are had with shock, produces old sense；Region beyond club head sole and striking surface is seldom contacted with hard thing
Or friction, can keep such as new state, but glossiness height generation is dazzling harmful effect to use, and Gao Zedugao does not possess height
The elegant sensation of shelves.
General way is to adhere to one layer of high molecular Matte film in part club head and overall club, and Matte film is divided into
Two kinds：A kind of is matting resin of the addition with special construction and group in base coating, and another kind is in base coating
Add some inorganic matter flatting silicas.But the matt film of polymer-based bottom material is easy to wear or wears, and produces shabby sense.And mesh
The striking surface of preceding glof club head, no matter Integral alloy material or coating, its hardness is all not enough to long-term violent of reply
Golf driving acts.
The content of the invention
A kind of the defects of it is an object of the invention to overcome the prior art, there is provided surface of golf club head composite film coating
And film plating process, glof club head integral surface have the metal-plated of the coat of metal, golf clubs head batting surface and bottom

Base butynol 1-3g, butynediols 1-2g, cerium chloride 0.1-0.5g, lanthanum chloride 0.1-0.5；Reagent, remaining matter are added except more than
Measure as ultra-pure water, after electroplating processes liquid configures, the high-hardness inorganic thing micron granularity particle of addition accounts for electroplating processes liquid
Product percentage is 1-3vol.%.
Optionally, high-hardness inorganic thing micron granularity particle for diamond, silica, corundum, titanium nitride, garnet or
One or more in carborundum, and size distribution D50 is at 0.4-0.7 μm.
Optionally, high-hardness inorganic nitride layer is diamond, carborundum or titanium nitride layer, and thickness is 1-4 μm.
Preferably, high-hardness inorganic thing micron granularity particle and high-hardness inorganic nitride layer are same compounds.
Processing further alternative, that high-hardness inorganic nitride layer passes through magnetically controlled sputter method：
A, substrate is positioned over and heated the substrate, install target before clear up target, using argon gas take away surface dust and
Impurity,
B, mechanical vacuum pumping sputtering chamber vacuum is used first, after air pressure is less than 10Pa, is driven molecule turbine pump, is evacuated down to
7×10-4After Pa, prepare sputtering and complete,
C, working gas is argon gas in sputter procedure, and the optional scope 0.1-1.5Pa of air pressure, radio frequency power range 60-
200W, 20-200 DEG C of base reservoir temperature scope.
The invention has the advantages that glof club head integral surface has the coat of metal, the hard of glof club head is lifted
Degree, and can be as the transition zone between high-hardness inorganic nitride layer and glof club head.High-hardness inorganic is mixed in the coat of metal
After thing micron granularity particle, the hardness of the coat of metal is can further improve, while cause the coat of metal that there is matte effect.Gao Er
Also there is high-hardness inorganic nitride layer on the striking surface and bottom metal coating of husband's club head, can significantly lift glof club head
Striking surface and the hardness of bottom so that the breakage and abrasion of striking surface and bottom decline to a great extent.
