Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a powder metallurgy preparation method of a nickel-based ceramic cylinder liner. Background technique [0002] Under complex and harsh working conditions, the cylinder liner of the drilling pump is prone to early failure, resulting in high drilling costs. The study found that insufficient wear resistance was the main reason. In order to improve the wear resistance of the cylinder liner, ceramic materials are often used in the prior art, but the fragile nature of the ceramic material affects the service life of the cylinder liner. In addition, the wear resistance of bimetallic cylinder liners is better than that of ordinary cylinder liners, but the domestic service life is only 200~400 hours. In recent years, when drilling under complex geological conditions such as deep wells, hard rock formations, and ocean drilling, the jet drilling technology under the conditions of high ...
