Abstract

The invention relates to a high-temperature resistant, high-speed wear resistant and self-lubricating chemical composite solution and a preparation and coating method thereof. The high-temperature resistant, high-speed wear resistant and self-lubricating chemical composite solution is prepared from nickel chloride, sodium molybdate, sodium borohydride, one or two complexing agents, sodium hydroxide, one or two stabilizing agents and deionized water according to weight parts. The preparation and coating method comprises the following steps of preparing a nickel-boron-molybdenum alloy, and coating the nickel-boron-molybdenum alloy on the surface of a steel collar so that the steel collar with the nickel-boron-molybdenum alloy has the hardness reaching above HV1300, and has good self-lubricating properties and high-speed wear resistance. The greatest feature of the high-temperature resistant, high-speed wear resistant and self-lubricating chemical composite solution comprises that after coating, the coated steel collar has the hardness reaching above HV1300 without heat treatment. The high-temperature resistant, high-speed wear resistant and self-lubricating chemical composite solution and the preparation and coating method are suitable for a thin workpiece having high precision.

Description

[0001] technical field cotton [0002] The invention relates to the technical field of spinning, in particular to the process of plating on the steel ring of cotton spinning. Background technique [0003] Cotton spinning steel ring has a speed of up to 10,000 to 20,000 revolutions per minute due to its track and copper ring. In order to prevent the temperature from being too high, the current measure is to plate a layer of chromium and polytetrafluoroethylene on its surface. However, its hardness only reaches HV600, and its wear resistance is not good, which limits high-speed work, and disconnection occurs from time to time. [0004] Chinese patent "a wear-resistant Ni-Cr nanocomposite coating and its preparation method and application", patent number: 201010543027.7. Disclosed are a wear-resistant Ni-Cr nanocomposite coating, a preparation method and application. The composition of the composite coating is nanometer-sized metal Ni and Cr, and the content of Cr is 8-12 part...
