Embodiment 1

[0022] A preparation method of manganese-nickel-cobalt-palladium-gold solder, comprising the following steps: Step 1, according to the composition of Mn 65.4%, Ni 17.11%, Co 12.48%, Pd 2%, Au 1.0%, Ti 1.0% and Al 1.0%. Take each component by weighing, and the balance is impurity components, wherein, the particle size of Mn, Ni, Co, Pd, Ti and Al is 250 mesh; the four components of Mn, Ni, Co and Pd that are weighed are uniformly mixed together, spare;

[0023] Step 2. Put the mixed particles in step 1 into the dry ice alcohol solution, make the temperature of the particles reach -45°C, take out all the particles and put them in a ball mill, and grind them until the particle size is below 30°C under the condition that the particle temperature does not exceed 30°C. When the mesh is 400, stop grinding, wherein the grinding time is not less than 2 hours; then, dry the ground powder at 115°C under a nitrogen atmosphere until its moisture content is lower than 0.05%, and set aside; ...

Embodiment 3

[0037] A preparation method of manganese-nickel-cobalt-palladium-gold solder, comprising the following steps: step 1, according to the composition of Mn 61.04%, Ni 19%, Co 14%, Pd 2.33%, Au 1.2%, Ti 1.2% and Al 1.2%. Compare and weigh each component, and the balance is impurity components, wherein, the particle size of Mn, Ni, Co, Pd, Ti and Al is 300 mesh; then the four components of Mn, Ni, Co and Pd are uniformly weighed mixed together, set aside;

[0038] Step 2. Put the granules mixed in step 1 into the dry ice alcohol solution, make the granule temperature reach -55℃, take out all the granules and put them in a ball mill, and grind them until the particle size is below 30℃ under the condition that the granule temperature does not exceed 30℃. When the mesh size is 400, stop grinding, wherein the grinding time is not less than 2 hours; then, dry the ground powder at 113°C under a nitrogen atmosphere until its moisture content is lower than 0.05%, and set aside;

Abstract

The invention provides Mn-Ni-Co-Pd-Au brazing filler metal and a preparation method thereof. The brazing filler metal comprises, by weight, 61-66% of Mn, 15-19% of Ni, 12-14% of Co, 2-2.5% of Pd, 0.8-1.2% of Au, 0.8-1.2% of Ti, 0.8-1.2% of Al and the balance unavoidable impurities. The preparation method of the brazing filler metal comprises the steps that Mn, Ni, Co and Pd are made into a bulk metal mixture, then the mixture and Au, Ti and Al are melted in molten salt, and finally the mixture is cooled in a quartz tube. According to the brazing filler metal, the content of Au is low, and the cost is lower compared with Au-based brazing filler metal; the melting of the brazing filler metal is conducted in the molten salt, compared with traditional vacuum melting, the production cost is greatly saved, the method is environment protective, and the energy consumption is low; the price of the quartz tube is low, the melted brazing filler metal is extracted by the quartz tube, the fastness and convenience are achieved, and the using cost is low.

Description

technical field [0001] The invention relates to the technical field of welding materials, in particular to a manganese-nickel-cobalt-palladium-gold solder and a preparation method thereof. Background technique [0002] Gold-based solder has the advantages of strong corrosion resistance, low vapor pressure, good fluidity and wettability, etc. Au-Ni-based solder has a wide range of applications. Au-18Ni brazing filler metal is the brazing filler metal with the best brazing process performance and brazing joint comprehensive performance and the most widely used brazing filler metal in Au-Ni series brazing filler metal. Its outstanding advantages are: it has good wetting to various metals Its brazing joints have high strength, excellent corrosion resistance and good high temperature creep resistance, and are widely used in the electronics industry, aircraft, missile and satellite manufacturing. But in Au-18Ni solder, the content of gold is very high and the cost is high. Cont...
