Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and embodiments.
Refering to Fig. 3,4, an embodiment of the film plating process of metalwork of the present invention is walked comprising an adaptation step 101, a preparation Rapid 102, one material preparation step 103 and an operation steps 104.In the present embodiment, the metalwork 8 is that spy is made in advance The annular wafer metal of scale cun, and in such a way that the nickel plating solution containing diamond particles carries out plated film to annular wafer metal Explanation.
The adaptation step 101 is the diamond particles that 30 grams are added in every 100 milliliters of a plating solution, and it is molten to form a plated film Liquid 9.Wherein, which has a main salt class, a reducing agent and a solvent, which be somebody's turn to do selected from nickel sulfate or nickel acetate Reducing agent is gently to change sodium, borine or diazane selected from phosphite, boron.And the partial size of each diamond particles is 10 to 50 micro- Rice.Refering to Fig. 3 to Fig. 5, which is one filming equipment of preparation, which defines accommodating sky including one Between 300 the roller 4, one that is rollably set in the accommodating space 300 of tank 3, one stretch be placed in the accommodating space 300 and The heating in the accommodating space 300 and for heating the coated solution 9 is installed on the roller 4 air supply pipe 5 separately and one Device 6.The roller 4 extends along an axis L, and hexagonal including a section and define space 410 in one around axis L Ontology 41 and six protruded out respectively from the ontology 41 towards the interior space 410 and along axis L extend corner post 42, this There are body 41 six panel parts 411 engaging one another and multiple through-holes 412 through the panel part 411, the corner post 42 to divide It is not protruded out from the panel part 411 towards the interior space 410, and the section of each corner post 42 is triangular in shape.
The material preparation step 103 is placed in multiple metalworks 8 in the interior space 410 of the rollers 4, and in the tank The coated solution 9 is contained in 300.
Refering to Fig. 3, Fig. 4 and Fig. 6, which is first to open the heater 6, according to used coated solution 9 are formulated and adjust proper temperature.Then, according to the air supply pipe 5 supply should compressed gas dosage, with directly proportional relationship tune The rolling speed of the whole roller 4 rolls the roller 4 in the accommodating space 300 with axis L shaft.Such as Fig. 6 institute Show, rolling of the roller 4 in the tank 3, is to provide power by a motor 71, and be preferably driven by a gear set 72 Mode is reached, and the design of the mechanism of this part belong to related fields tool usually intellectual can be according to implementation environment, cooperation The factor of power-equipment etc. and the person of being readily accomplished, as long as being able to that the roller 4 is allowed to roll in the tank 3 really, not with Aforesaid way is limited.
When carrying out plated film in the present embodiment, the coated solution 9 is preferably made to maintain 90 degree Celsius, then according to described in The size and quantity of metalwork 8, and cooperate the estimated compressed gas scale of construction applied, make the roller 4 with speed appropriate rotation. In the present embodiment, 1 kilogram of compressed gas is preferably used, and the roller 4 is and the institute with 10 turns of speed per minute rotation The size for stating metalwork 8 is 1 to 10 centimeter, especially preferably based on 5 centimeters, and quantity be preferably then one time 500.Its In, which, which preferably selects, to react with the coated solution 9, and do not interfere with the redox reaction of plated film Air.The metalwork 8 can be because of the rolling of the roller 4, and the relationship stirred by the corner post 42, in the interior space 410 In uniformly roll.It in addition to this, more can be right also because entering the compressed gas in the interior space 410 by the through-hole 412 The metalwork 8 generates additional perturbed force, so that the metalwork 8 is easier to disperse each other in the interior space 410, Jin Erneng Uniformly and it is substantially contacted coated solution 9, uniformly plates the film containing diamond particles.
Refering to Fig. 7 and Fig. 8, plating has the metalwork 8 of the nickel film 802 containing diamond particles, that is, being formed has height coarse Spend and can be improved the gasket 800 of two inter-module linking steady characters.Due to the metalwork 8 preforming, therefore after carrying out plated film Additional waste material will not be generated, also due to the metalwork 8 after plated film does not need to carry out external force processing again, therefore plates attached nickel film 802 will not thus be damaged, and more effectively improve the quality of plated film.When the gasket 800 pad is placed in two inter-modules, due to The great friction coefficient of the gasket 800, when the component is by external force, which can generate high frictional force and avoid described Inter-module generates relative movement, thereby ensures that the linking steady character of the component.
