It is used widely in gold.
Up to the present, the preparation process of amorphous powdered alloy mainly has water fog method, aeroponics and using amorphous thin ribbon
The technique for crushing powder processed.Water fog method has big cooldown rate, can meet the requirement for preparing amorphous powder.However, in water mist
During change, the powder obtained easily forms oxide, and oxygen content is high, furthermore upon solidification of the molten metal, the vapor of generation
The surface of molten metal can be covered in, the presence of the vapor film reduces the core metal intensity of cooling for leading to melting, so as to
Prevent the problem of powder central part is from obtaining amorphous structure, influence device performance.Aeroponics are since intensity of cooling is limited, only
The strong amorphous powdered alloy of amorphous formation ability can be prepared, and production cost is high.The advantages of direct crush method, is to material
Selectivity is not strong, and stock utilization is high, but brittle annealing need to be carried out to amorphous thin ribbon, it is easy to since annealing unevenness causes strip
Internal crystallization change it is uneven, and the powder particle with acute angle is easily generated after broken, is the following process of powder
Bring difficulty.
And compared with liquisol quenching method, sputtering method prepare amorphous alloy material, galvanoplastic are more economical, and application range is also more
It is wide.The formation of Resisting Property of Brush Electroplating Coating plating of inherently making peace is identical, is all the metal ion in solution in cathode（Workpiece）
The process of upper electric discharge crystallization.But compared with plating, plated pen and workpiece have relative motion in Brush Plating, thus plated surface is not
It is whole that metal ion reduction crystallization, the knot but plated surface each point sparks when plated pen is in contact with it occur simultaneously
It is brilliant.Therefore, Brush Electroplating Technique has its unique distinction in process aspect, and feature can be summarized as follows：
1st, equipment is simple, does not need to coating bath, easy to carry, suitable for field and field repair.Particularly with large-scale, precision equipment
Scene do not disintegrate repair it is more with practical value；
2nd, simple for process, operation is flexible, does not need to the position of plating and not use many material protections；
3rd, in operating process, cathode has relative motion with anode, therefore allows using higher current density, it is used than slot plating
Current density is several times greater to tens times；
4th, metal ion content is high in plating solution, so plating product speed is fast（It is 5 times~10 times faster than slot plating）；
5th, have a plated pen of different model, and equipped with shape is different, insoluble anode not of uniform size, to various different geometries and
Complicated parts can all be repaired；
6th, expense is low, and economic benefit is big.
Invention content
In view of the above-mentioned problems, provide a kind of production technology based on brush nickel plating alloy amorphous powder.
The ingredient of the nickel alloy amorphous powder of the present invention is nickel 40-82 wt %, cobalt 8-30 wt%, iron 5-15 wt%, phosphorus
5-15 wt%。
The production technology of nickel alloy amorphous powder of the present invention.Include the following steps：
（1）Metal substrate selects and is plated the processing on surface：The elongation percentage at normal temperatures of metal substrate is not less than 10%, is plated
Mechanically or chemically derusting, degreasing can be used in surface；
（2）The composition of electric brush plating liquor：Nickel chloride or nickel sulfate 3-7.5 mol/L（It is preferred that 4-6 mol/L）, phosphoric acid 0.5-1.5
Mol/L, cobaltous sulfate or cobalt chloride 0.4-2.5 mol/L, ferrous sulfate or frerrous chloride 0.3-2 mol/L, phosphorous acid 0.2-1.5
Mol/L, additive 1-8g/L, soluble sulphate or chlorate 10-50 g/L, reducing agent 1-8g/L, excess water；
Above-mentioned additive is tartaric acid and the mixture of neopelex；
4 kinds of salt use homo-ion in above-mentioned electric brush plating liquor, that is, are soluble sulphate or chlorate；
Above-mentioned reducing agent is water-soluble；
（3）The preparation of nickel alloy amorphous deposit：Nickel alloy amorphous deposit is prepared using brush electroplating method, anode using graphite cake or
Stainless steel plate, the current density of electrode is 0.5-5 A/mm2（It is preferred that 1.5-3 A/mm2）, electrode speed of related movement is 5-20
m/min（It is preferred that 10-15m/min）, titrating hydrochloric acid or sulfuric acid solution makes plating solution Ph values be less than 3, and plating temperature is 40-75 DEG C,；
（4）Amorphous deposit is made to come off from metallic substrate surfaces using milling method, rolling reduction ratio is 4-10%；
（5）The amorphous deposit to come off is crushed using modes such as ball mill, particle breakers.When broken, ball mill, particle are broken
Broken machine should use and force the type of cooling or interval work mode, to prevent amorphous particle from generating larger Wen Sheng when broken, generation
Crystallization change；
（6）The nickel alloy amorphous powder of different thicknesses is sieved into using sieve.
Compared with prior art, the present invention has the following advantages：
1. compared with aeroponics and direct crush method, this technique has equipment investment few, simple for process, and energy is formed to non-crystaline amorphous metal
