Problems solved by technology

[0005] However, cobalt is a high-temperature heat-resistant alloy with a small thermal conductivity. When processing cobalt targets, the local temperature rises high, and the tool is easy to wear. When pure cobalt is processed, it is prone to rebound, and the tool is easy to break. , nitrogen reaction to form oxides, which is not conducive to processing

Embodiment Construction

[0026] The inventor found that domestic processing of cobalt targets generally adopts ordinary milling methods, and there is no special research on processing parameters, and the settings are relatively random, which are generally the same as processing other targets such as chromium targets and titanium targets; for example, the processing tool speed is 450~ 550 rpm, the feed rate is 0.8-1.0 mm / time, and the feed speed is 50-100 mm / min. However, due to the high hardness and high brittleness of the cobalt target at room temperature, it is easy to generate large stress when using the existing technology to process the cobalt target, and the cooling effect cannot be guaranteed, which is easy to cause tool chipping, and it is easy to interact with oxygen and hydrogen at high temperature. , Nitrogen reaction to form oxides.

[0027] In view of the above problems, the inventor proposed a method for processing cobalt targets. By using high speed, low feed rate, and spraying cooling ...

Abstract

The invention relates to a processing method for a cobalt target material, which comprises the following steps of: providing the cobalt target material; cutting the surface of the cobalt target material by using a PCBN (Polycrystalline Cubic Boron Nitride) knife, wherein the PCBN knife has a rotating speed range of 250-300 revolutions / second, a feed range of 0.03-0.08 millimeter / revolution and a back cutting depth range of 0.01-0.05 millimeter, wherein a spraying manner is adopted for cooling in the cutting process. The processing method for the cobalt target material has the advantages that the processing effect can be improved; and the problems in the prior art that when the cobalt target material is processed, the knife is easy to abrade, even break, and the cobalt target material easily reacts with oxygen, hydrogen and nitrogen at a high temperature to form an oxide are solved.

Description

technical field [0001] The invention relates to the field of target processing, in particular to a method for processing a cobalt target. Background technique [0002] Cobalt-based alloys are a general term for alloys made of cobalt and one or more of chromium, tungsten, iron, and nickel. The most widely used alloys in aerospace technology are cobalt-based alloys. This is because at high temperatures, cobalt-based alloys can form refractory carbides. These carbides are not easy to turn into solid solutions, and the diffusion activity is small. The temperature is above 1038°C , the superiority of cobalt-based alloys is fully demonstrated. The structural materials of aviation turbines use cobalt-based alloys containing 20% ​​to 27% chromium, which can achieve high oxidation resistance without protective coatings. [0003] Metal cobalt is mainly used to make alloys. A tool containing a certain amount of cobalt can significantly improve the wear resistance and cutting perform...
