Abstract

The invention provides a zirconium oxide ceramic cylinder jacket material, which comprises 65-75wt% of zirconium oxide, 3-6wt% of cerium oxide, 1-3wt% of yttrium oxide, 20-30wt% of aluminum oxide, and 0.5-2wt% of titanium dioxide. The invention also provides a preparation method for the zirconium oxide ceramic cylinder jacket material. The zirconium oxide ceramic cylinder jacket material provided by the present invention has higher strength, toughness and thermal shock resistance, and is able to resist wear, corrosion and high temperature. inner liner of slurry pumping cylinder sleeve prepared from the zirconium oxide ceramic cylinder jacket material has the following advantages that (1) service life is long, performance-price ratio is high, thereby reducing equipment cost consumption, greatly reducing frequency of shutdown to maintain cylinder jacket, reducing economical loss due to stop production and maintenance, and lightening labor intensity of workers; and (2) wearing for piston in the cylinder jacket is reduced, service life of the piston is prolonged, and piston cost is saved.

Description

technical field [0001] The invention relates to a ceramic material, in particular to a zirconia ceramic cylinder liner material and a preparation method thereof. Background technique [0002] In the current oil drilling, the mud pump is the "heart" of the drilling workbench, and the cylinder liner in the mud pump is a vulnerable part that consumes a lot of energy. At present, the cylinder liners in mud pumps used in oil fields are basically composite metal cylinder liners composed of low-carbon steel outer casings and high-chromium cast iron linings. Due to harsh working conditions, the service life of metal cylinder liners is short, so Frequent replacement will seriously affect production efficiency, and increase equipment cost consumption, resulting in great economic losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a zirconia ceramic cylinder liner material and a preparation method of the zirconia ceram...
