Problems solved by technology
Forged cobalt-based alloy artificial joints are mostly magnetic at present, and a few micro-magnetic ones have not seen a large number of commercial applications because other performance indicators are lower than national standards.

[0050] 1. Preparation of WKG-1A alloy
[0051] Using a 100kg-class vacuum reactor to melt 70kg of ingredients, the melting process is as follows:
[0052] S1. Take the middle limit value of the weight percentage of various elements of the new alloy of the artificial joint and multiply it by the total weight of the smelted charge to obtain the charge weight of the corresponding element, and weigh the charge of each element according to the calculated charge weight of each element. required metal raw materials. The weight is weighed to the nearest gram. The corresponding element content of the metal raw materials shall not be less than 99.9%.
[0053] S2. Put the weighed charge of each element into the crucible of the melting furnace. In order, the charge of elements with low melting point is placed at the bottom, and the charge of elements with high melting point is placed at the top; close the cover of the melting furnace. Turn on the vacuum pump.
[0054] S3. When the vac...

Abstract
The invention relates to a novel artificial joint alloy and a smelting process therefor. The alloy can be used for other medical human implants. The novel artificial joint alloy has no magnetism or toxicity; other properties of the novel artificial joint alloy are equivalent to those of a cobalt-based alloy; in addition, the novel artificial joint alloy is easy to cast and forge and still has no magnetism after being forged; besides, fewer precious metals are used, and the qualification rate of a finished product, brought by easiness in casing and forging, is high, so the consumption of energy and materials is less; from a long-term point of view, the alloy belongs to resource-saving type and environmental-protection type, and has sustainable development significance. In addition, all component elements of the alloy are early applied in an existing artificial joint alloy, therefore, the availability of the novel artificial joint alloy in the medical human implants does not need to be clinically verified.
Description
technical field [0001] The invention relates to the technical field of artificial joints, in particular to a new type of alloy for artificial joints and a melting process thereof. Background technique [0002] The existing artificial joint alloys can be divided into two categories, one is titanium-based alloys and the other is cobalt-based alloys. Cobalt-based alloys are further divided into cast cobalt-based alloys and wrought cobalt-based alloys. [0003] One of the most prominent advantages of titanium-based alloys is that they are non-magnetic. This is important, especially as the times evolve. The reasons for implanting artificial joints in humans were mostly caused by accident trauma in the early stage. And now, it is more and more caused by accidents in daily life due to the aging of the population that more and more people suffer from osteoporosis. Even the modern lifestyle of young people is causing osteoporosis at a younger age. More and more young people in a...
