Background technology
The making quality of plating nickel cobalt diamond bit decides laser gyro cavity discharge loop pore processing and forming
Quality, and the crudy of electroplated diamond bit and the performance of bath solution are closely bound up.Covering power is bath solution
One Key Performance Indicator, so-called covering power refers to that plating solution can deposit plating at the calixconcavity of complicated shape part or in deep hole
The ability of layer, is also covering power.The area that the coat of metal of deposition covers part is bigger, and the covering power of the plating solution is got over
It is good.The endoporus for directly affecting electroplated diamond cutter is coated with quality by depth capability, and endoporus, which is coated with poor quality, will cause interior
Hole sand fallout, brings a series of problems：Cutter life is reduced, and hole wall is scratched etc..
At present, the detection method of bath solution covering power has negative pole of right angle method and endoporus method.Negative pole of right angle method passes through system
Make negative pole of right angle, the percentage of coating area coverage is calculated after being electroplated to negative pole of right angle surface, percentage is bigger, cover energy
Power is better, but this method areal calculation is bothered, and is unsuitable for evaluating the covering power of capillary drill bath solution.Endoporus method
It is that hollow pipe is electroplated, the plating layer depth of endoporus is observed after plating, this method is relatively adapted to evaluate the plating of capillary drill
The covering power of tank liquor, but hollow pipe, which is coated with rear endoporus, to be coated with depth and is difficult to accurate measurement, causes the covering to bath solution
The error of quality appraisement of ability is big.
The content of the invention
The purpose of the present invention is：A kind of quick test evaluation method of nickel cobalt bath solution covering power is proposed, so as to accurate
The covering power of capillary drill bath solution is evaluated on ground, improves the electroplating quality of diamond bit, and then improve laser gyro
Cavity discharge loop pore processing and forming quality.
The technical scheme is that：A kind of nickel cobalt bath solution covering power method for rapidly testing, it is characterised in that：Survey
The step of examination, is as follows：
1st, plating test specimen is prepared：Along axis profile cutting it is two semicanals by a stainless steel tube 1, is left semicanal 2 respectively
With right semicanal 3, the external diameter of stainless steel tube 1 is not more than 5mm, and wall thickness is 0.5mm~1mm；By the parting of left semicanal 2 and right semicanal 3
Face is combined to form a homogeneous tube, as plating test specimen, is wound, is formed in the middle part of the external cylindrical surface of plating test specimen with insulating tape
Protective layer 5, protective layer 5 to one section of exposed plating section 6 is reserved between plating test specimen lower port, electroplate the length 3mm of section 6~
10mm, protective layer 5 reserves one section of exposed electrode section between plating test specimen upper port；
2nd, plating experiment：Plating test specimen is put into progress plating experiment in electroplating bath.Wherein, tank liquor formula is seven water sulfuric acid
Nickel 340g/l, cobalt sulfate 40g/l, nickel chloride 40g/l, boric acid 30g/l, lauryl sodium sulfate 0.3g/l, electroplating parameter
For current density 1.5A/dm2, electroplating time is 10min.
3rd, covering power is evaluated：
3.1st, coating length is measured：The protective layer 5 for electroplating test specimen is removed, plating test specimen is broken up into the left He of semicanal 2
Right semicanal 3, the length b of the length a of the left endoporus coating 7 of semicanal 2, the endoporus coating 8 of right semicanal 3 is measured with slide calliper rule or precise observations instrument
And the length c of outer wall coating 9；
3.2nd, covering power coefficient T is calculated：
T=0.5 (a+b)/c, T are percentage, and the covering power of the bigger bath solution of T values is better.
It is an advantage of the invention that：A kind of quick test evaluation method of nickel cobalt bath solution covering power is proposed, can be accurate
The covering power of capillary drill bath solution is evaluated on ground, improves the electroplating quality of diamond bit, and then improve laser
Gyroscope cavity discharge loop pore processing and forming quality.
