Abstract
The invention discloses a diamond coating method which comprises the following steps: firstly, depositing a layer of first coating comprising strong carbide forming elements on the surface of diamond by a vacuum micro-evaporation process; secondly, depositing a layer of second coating comprising carbide forming elements with relatively good oxidation resistance on the first coating by a vacuum micro-evaporation and powder metallurgical coverage process; finally, electroplating the second coating with a layer of third coating comprising Ni or Cu. By integrating the characteristics and interactions of the first to third coatings, the strength of bonding between the diamond and a matrix is greatly improved and the diamond hardly falls off when in use; moreover, remarkable bulges are formed at the peripheries of diamond particles, so that the exposure is greatly increased, the service life of a diamond tool is greatly prolonged, and the processing efficiency of the diamond tool is greatly improved.
Description
Technical field
The present invention relates to plated film field, specifically a kind of adamantine film coating method.
Background technology
Diamond has the performance of the excellences such as hardness is high, wear resistance is strong, skin friction coefficient is low, thermal conductivity is good, is widely used in many fields such as cutting tool and grinding tool.But owing to there is higher interfacial energy between diamond and most metals, the interface bond strength therefore between diamond and common metal bonding agent is very little; And adamantine thermal expansivity is far smaller than the coefficient of expansion of metallic bond, under the effect of processing arc district temperature, due to the thermal expansion degree varies sample of bonding agent and diamond particles, bonding agent is caused to reduce adamantine hold, cause coming off of diamond particles, cause the improper inefficacy of diamond tool.
In order to overcome the above problems; by the method at metals such as diamond surface plating Ti, Mo, W, Cr; realize adamantine effective holding; the interfacial energy between diamond and metallic bond can not only be effectively reduced; increase the roughness of diamond surface; coating can also play insulation blocking effect to diamond; at high temperature can prevent diamond from oxidation or greying occurring; improve adamantine thermostability; therefore effectively can reduce that instrument is in use adamantine to come off, thus improve work-ing life and working (machining) efficiency.
Domestic-developed goes out the diamond abrasive of coating surface Ti, and the life-span of diamond tool and working (machining) efficiency are greatly enhanced.But find after deliberation, the diamond oxidizing temperature due to plating titanium is 780 DEG C, existing titanium base coating material due to its high-temperature oxidation resistance poor, be not enough to protect the diamond in high ferro carcass, during use, still have a large amount of coming off.
Summary of the invention
The object of this invention is to provide a kind of adamantine film coating method, it can make the carcass around diamond obtain very large strengthening, diamond difficult drop-off during use.
To achieve these goals, the present invention adopts following technical scheme:
A kind of adamantine film coating method, realizes as follows:
S1: adopt vacuum micro-method of evaporation to deposit at diamond surface the first coating that one deck is made up of carbide, the thickness of this first coating be 100 ?200nm;
S2: add powder metallurgy cladding process with the micro-evaporation of vacuum and deposit the second coating that one deck is made up of the carbide forming element that oxidation-resistance is higher on above-mentioned first coating, the thickness of this second coating be 100 ?300nm;
S3: the 3rd coating plating layer of Ni or Cu formation on above-mentioned second coating with electric plating method, the thickness of this 3rd coating is 10 ?500 μm.
In above-mentioned steps S1, carbide is Ti or Cr.
In above-mentioned steps S2, the carbide forming element that oxidation-resistance is higher is W, Mo or Si.
After adopting such scheme, adamantine film coating method of the present invention, because the carbide in the first coating can form carbide with diamond thus can change diamond surface Bonding Type, changes diamond surface wettability.Then on the basis of the first coating, deposit the second coating that one deck is made up of the carbide forming element that oxidation-resistance is higher again, this second coating and the first coating form Chemical bond, not only improve adamantine sinterability and anti-matrix erosional competency like this, the defect of not wrapping up completely of the first coating can also be filled up further, and the anti-oxidation metal in the second coating has vattability, its high-temperature oxidation resistance is better.In 3rd coating, because the metal level densifications such as nickel plating are wear-resisting, the carcass around diamond is made to obtain very large strengthening.
The comprehensively feature of above-mentioned first, second, third coating and effect each other, bonding strength between diamond and carcass is improved greatly, diamond is difficult drop-off in use, and formed obviously protruding around diamond particles, go out sword greatly to increase, life-span and the working (machining) efficiency of diamond tool are greatly enhanced.
Embodiment
