Abstract
The invention belongs to the technical field of repairing titanium alloy in nonferrous materials by welding and relates to a method for adopting copper-based solder to repair titanium alloy castings by welding. The method adopts the following hard solder ingredients according to weight percentage: 0-5 percent of Al; 0-5 percent of Ni; 0-26 percent of Ti; and the balance of Cu. -40 to 200 meshes of single element particles or powder is used to be stirred mechanically and mixed uniformly; then the solder powder is laid and filled on the fault location of the titanium alloy casting; the mixed solution of organic rubber and acetone is used to fix the solder powder on the surface of the fault location of the titanium alloy casting; and at the temperature of 910-960 DEG C, hard solder, voltaic arc or oxy-acetylene flame heating is adopted to implement weld repairs on the fault location of the titanium alloy casting. By using the copper-based alloy as the solder, the method leads the main element Cu in the solder and the element Ti in the solder or in the titanium alloy casting repaired by welding to conduct eutectic reaction with each other, thus obviously reducing the price of raw materials and simplifying the preparation process.
Description
Technical field
The invention belongs to the nonferrous materials technical field, relate to a kind of method that adopts copper-based solder to repair titanium alloy castings by welding.
Background technology
The soldering tech of titanium alloy begins to obtain large development from the seventies, Ti-Cu-Ni, Ti-Zr-Cu, Ti-Zr-Ni have been formed at present respectively, Ti-Zr-Be, Ti-Cu-Ni-Be, Ti-Zr-Cu-Ni, Ti-Ni, the solder of systems such as Ti-Ni-Ag (O.Botstein, A.Rabinkin, Brazing oftitanium-based alloys with amorphous 25wt%Ti-25wt%Zr-50wt%Cu fillermetal, Materials Science﹠amp; Engineering A, vol.A188, No.1-2,1994, P305-315; H.Inoue, T.Ogawa, Studying on welding of titanium alloys (Report 2), Quarterly Journal of the Japan Welding Society, vol.9, No.1,1991, P 136-142; H.Steffens, E.Degelmann, Simplified high-temperaturebrazing process for titanium and titanium alloys using an amorphous brazingfiller metal, Schweissen und Schneiden, vol.42, No.5,1990, P70-71; Guo Wanlin, the activity of titanium based solder and physicochemical property comparative study, material science and technology, vol.7, supplementary issue, 1999, P217-219; O.Taguchi, Y.Lijima, K.Hirano, Reaction diffusionin the Cu-Ti system, Journal ofthe Japan Institute ofMetals, vol.54, No.6,1990, P619-627; Lan Shiwei, titanium alloy contact reaction brazing, international airline, 1982, (8): P 44-46).
Titanium alloy casting defective occurs through regular meeting, and adopting welding repair method to remedy is the process of very economical.Use above-mentioned titanium based solder, can be used on the principle titanium alloy casting defective is carried out REPAIR WELDING.But, because the cost price of Titanium is higher, so the cost of raw material of titanium based solder own is just high, consider titanium based solder alloy powder or fast quenching chilling paper tinsel band manufacturing procedure complexity and qualification rate problem again, preparation technology's cost of titanium based solder alloy powder or fast quenching chilling paper tinsel band is just higher, therefore, the rehabilitation cost to titanium alloy casting is very high.
Summary of the invention
The objective of the invention is to propose a kind of a kind of method of adopting copper-based solder to repair titanium alloy castings by welding cheap to the titanium alloy casting rehabilitation cost.
Technical scheme of the present invention is: adopt solder composition percentage by weight to be: Al:0～5%; Ni:0～5%; Ti:0～26%; surplus is the solder of Cu; use-40 orders～200 purpose single element particle or powder; mechanical agitation mixes; again solder powder shop is filled out fault location at titanium alloy casting; with organic gel and acetone mixed liquor the solder powder is fixed on the blemish surface of titanium alloy casting, under 910～960 ℃ of temperature, the titanium alloy casting defective is implemented repair by welding with soldering or electric arc or oxy-acetylene flame heating.
Advantage that the present invention has and beneficial effect; the present invention uses acid bronze alloy as cored solder; make in essential element Cu in the solder and the solder or eutectic reaction takes place the Ti element in the titanium alloy casting of soldered repairing each other; make solder under 910～960 ℃ of temperature, to carry out REPAIR WELDING to the titanium alloy casting defective; element al and Ni are alloying elements in the solder; only need to use single element particle or powder (40 orders～200 orders) alloyage solder, can use after mechanical agitation is even.With respect to the titanium based solder alloy powder or the fast quenching chilling paper tinsel band that used in the past often, not only cost of material is than the obvious reduction of titanium based solder, and preparation technology simplifies greatly, and therefore the cost for titanium alloy casting defective REPAIR WELDING reduces significantly.The repair by welding of carrying out the cast titanium alloy golf club with employing copper base brazing material of the present invention is an example, adopts the cost of this programme REPAIR WELDING to be about 1/10～1/20 of original employing alloy powder or fast quenching chilling paper tinsel band forms titanium based solder.
