Abstract
The metal nickel is used as anode material, metal nickel plate is used as cathode deposition mother body, and in the electroforming plating liquor the reinforcing body and codepositino promotor made up by using cationic fluorocarbon surfactant, triethanolamine, hexamethyne tetramine and sulfourea are added, then powered on to make metal nickel ions and reinforcing body codeposit on the cathode mother body, then the composite electroformed plating layer can be stripped from cathode to obtain the integrally-reinforced nickel base compostion material with low cost and excellent performance.
Description
Technical field:
The present invention designs a kind of composite electroforming process of nickel-base composite material, belongs to the composite plating technology field.
Background technology:
The method that is used to prepare discontinuous enhancing metal-base composites at present is a lot, as (" metal-base composites " Zhang Guoding, Zhao Changzheng such as diffusion bonding method (solid state process), molten metal infiltration method (liquid infiltration method), casting, high energy forming methods, press of Shanghai Communications University, 1996).These preparation methods all need at high temperature carry out, and make metallic matrix easily and strengthen serious surface reaction, the oxidizing reaction of generation between the body and service temperature is higher, cause metallic matrix and the structure and the degradation that strengthen body interface.Simultaneously, in preparation process, strengthen that body is perishable under comparatively high temps, embrittlement, lose intensity, thus the forfeiture strengthening effect.And for prepare metal-base composites with composite plating method, one of them shortcoming is exactly that prepared composite deposite is thinner, in most cases only be at component surface plating one deck matrix material, it is compared with bulk material, its range of application narrower (" composite deposite " Guo Hetong, Zhang San unit, press of University Of Tianjin, 1991).
Summary of the invention:
The objective of the invention is to some shortcomings at conventional metals based composites preparation method and composite plating process, a kind of new nickel-base composite material electroforming preparing process is provided, in conjunction with complex electrodeposit axiom and galvanoplastics, relatively low at the technology cost, under the not high situation of service temperature, the preparation enhanced granule is evenly distributed, the relative common electrical coated coating of integral thickness is big, the nickel-base composite material of excellent performance.
Technical scheme of the present invention is: based on complex electrodeposit axiom, make anode material with metallic nickel, thickness be the metal nickel plate of 1mm as the cathodic deposition parent, in the composite plating groove, select the preparation electroform bath.(concentration range in electroform bath is 5～100g/L) to add in the electroform bath will to strengthen body, and adding codeposition promotor, energising makes metallic nickel ions and strengthens the body common deposited on the negative electrode parent then, at last complex electroform coating is peeled off and is obtained the overall enhanced nickel-base composite material from negative electrode.
Electroform bath of the present invention can be selected vitriol electroforming solution, sulfamate, vitriol-muriate and high speed electroformed nickel electroforming solution respectively for use.Strengthen body and can select different kinds for use, as particle (as particles such as SiC, BN, graphite, PFTE), whisker (as the SiC whisker) and staple fibre (as graphite fibre, carbon fiber etc.), to prepare multiple enhancing nickel-base composite material.The codeposition promotor of being adopted is the mixed preparation of cation fluorine carbon surface active agent (FC), trolamine, hexamethylenetetramine and four kinds of additives of thiocarbamide gained, its composition proportion in electroform bath is: cation fluorine carbon surface active agent 1～5g/L, trolamine 30～80ml/L, hexamethylenetetramine 10～50g/L, thiocarbamide 0～30mg/L.
The present invention carries out in the aqueous solution, and temperature is no more than 90 ℃, and only needs to transform slightly on general electroplating device basis and just can be used as this composite electroformed equipment, and cost is lower.Can effectively control the enhancing content of body in nickel-base composite material and the degree of uniformity of distribution by the adjusting process parameter in addition, thereby make material in a big way, keep better physical and mechanical property.The nickel-base composite material enhanced granule of the present invention's preparation is evenly distributed, the relative common electrical coated coating of integral thickness is big, excellent performance.
