Embodiment Construction

[0016] specific implementation plan

[0017] A cobalt-based alloy material is made of raw materials according to the following mass percentages: Co, 45.5%; Cr, 26; Ni, 2%; Mo, 1%; W, 17%, Fe, 3.5%; Mn, 0.5 %; Si, 2.5%; C, 1%;

[0018] A method for manufacturing a cobalt-based alloy material, comprising the following steps:

[0019] 1) Prepare the corresponding contents of Co, Cr, Ni, Mo, W, Fe, Mn, Si and C according to the weight percentage of the chemical composition of the alloy;

[0020] 2) Put Co, Cr, Ni, Mo, W, Fe, Mn, Si and C into a high-energy ball mill and mill for 6 hours, then dry and sieve to obtain a 300-mesh powder;

[0021] 3) Add paraffin wax molding agent to the material obtained in step 2) according to the injection molding requirements, stir at 100°C for 60 minutes and then cool;

[0022] 4) Break the material obtained after cooling in step 3) into 60-mesh particles, and inject it into a green product through an injection machine;

[0023] 5) Put the gr...

Abstract

The invention discloses a cobalt-base alloy material. The cobalt-base alloy material is prepared from the following raw materials in percentage by mass: 40-70% of Co, 20-30% of Cr, 1-10% of Ni, 0.5-10% of Mo, 1-20% of W, 1-5% of Fe, 0.2-0.5% of Mn, 0.5-4% of Si and 0.4-2% of C. The invention also provides a manufacturing method of the cobalt-base alloy material. The method comprises the following steps: preparing an alloy material with corresponding content according to the weight percentages of chemical components of the alloy; performing ball-milling on the alloy material to obtain powder; then adding a forming agent; stirring and cooling; crushing an obtained material into particles; injecting to obtain a product green blank by virtue of an injection molding machine; putting the green blank into a vacuum degumming integrated furnace, and sintering to obtain a product. The cobalt-base alloy material disclosed by the invention is easy to process, has more excellent wear resistance and corrosion resistance than those of stainless steel, and can be widely applied to the field of clocks and watches and jewelries.

Description

technical field [0001] The invention relates to the field of nonferrous metal materials and their preparation and molding, in particular to a cobalt-based alloy material and a manufacturing method thereof. Background technique [0002] Platinum (Pt for short) is a natural pure white white precious metal, known as the king of precious metals. Platinum is the rarest jewelry metal in the world. Platinum is only produced in a few places such as South Africa and Russia in the world, and its global storage capacity is only one-thirtieth of that of gold. Tons of ore, after more than 150 processes, took several months, and the extracted platinum can only be made into a simple ring weighing a few grams. Therefore, there is an urgent need for a platinum-like material to be used in the field of watch jewelry and jewelry. [0003] At present, the manufacturing method of cobalt-based alloy materials is mainly to cast products through high-temperature casting, which can only cast produc...
