Problems solved by technology

When using plasma electrolytic oxidation technology and solid lubricating coating deposition technology for composite treatment, it is necessary to repeatedly clamp the sounding component, which can easily cause deformation of the sounding component, thereby affecting its matching accuracy with the sounding component
At the same time, the surface finish of the sounding components is required. When the plasma electrolytic oxidation treatment is used, a rough and porous ceramic surface will be formed on the surface, and it is difficult to remove it through subsequent secondary processing, which will also affect the matching accuracy of the sounding components.

Abstract

The invention discloses a coating for a frequency-adjustable high-sound-intensity soot blower sound production assembly and a preparation method for the coating. The coating is arranged on the soot blower sound production assembly, and comprises an oxidation ceramic layer and nano solid lubricant particles, wherein the interior of the oxidation ceramic layer is filled with the nano solid lubricant particles; the oxidation ceramic layer is a hard anodizing coating; the nano solid lubricant particles comprise nano MoS2 particles or nano graphite particles. According to the coating, the nano solid lubricant particles are uniformly dispersed in an electrolyte solution, and a continuous oxidation ceramic layer / solid lubricant composite coating can be formed on the inner surface of an outer cylindrical thin-walled part in one time, repeated tooling times of the outer cylindrical thin-walled part are reduced, so that mismatching of a sound production assembly due to the deformation of the thin-walled part is avoided.

Description

technical field [0001] The invention relates to a wear-resisting and anti-friction technology for titanium alloy thin-wall workpieces vibrating at a wide frequency, in particular to a coating used for a sounding component of a frequency-adjustable high-sonic-intensity soot blower and a preparation method thereof. Background technique [0002] The frequency-adjustable high-sound intensity sonic soot blower is a new type of sonic soot blower developed based on high-sound-intensity sound generation and automatic control technology. It can be used for soot blowing on the heating surface of boilers in power plants. , the sounding component is two concentric cylindrical thin-walled parts (thickness 0.8 ~ 1.5mm), when the frequency-adjustable high-sonic soot blower is working, the airflow reaches the sounding component after being filtered, and the control system controls the reciprocating of the sounding component through electrical signals Vibrate, change to produce the desired a...
