Embodiment 1

[0052] In step (1), the joint bearing uses TC11 titanium alloy as the base material of the inner ring, and TC4 titanium alloy as the base material of the outer ring, and polishes the surface of the bearing base to ensure that the surface roughness of the base is Ra≤0.05 μm.

[0053] Step (2), ultrasonically clean the inner ring of the joint bearing for 15 minutes to remove burrs and other stains on the surface of the inner ring substrate, put the workpiece in acetone for dehydration treatment, fully dry the surface of the workpiece and put it into the vacuum chamber of the coating machine Prepare the coating in the middle; use the multi-arc ion plating method to deposit TiN coating on the outer spherical substrate of the inner ring, the thickness of the TiN transition layer is 1 μm; then deposit a TiAlN hard coating on the TiN transition layer, the thickness of the TiAlN hard coating is 3 μm ; Deposition of MoS on TiAlN coating by magnetron sputtering 2 Soft coating, MoS 2 Th...

Embodiment 2

[0059] In step (1), the joint bearing uses TC11 titanium alloy as the base material of the inner ring, and TC4 titanium alloy as the base material of the outer ring, and polishes the surface of the bearing base to ensure that the surface roughness of the base is Ra≤0.05 μm.

[0060] Step (2), ultrasonically clean the inner ring of the spherical plain bearing for 20 minutes to remove burrs and other stains on the surface of the inner ring substrate, put the workpiece in acetone for dehydration treatment, fully dry the surface of the workpiece and put it into the vacuum chamber of the coating machine prepare for coating;

[0061] The multi-arc ion plating method is used to deposit TiN coating on the outer spherical substrate of the inner ring, and the thickness of the TiN transition layer is 2 μm; then, a TiAlSiN hard coating is deposited on the TiN transition layer, and the thickness of the TiAlSiN hard coating is 5 μm; Deposition of WS on TiAlSiN coating by sputtering 2 Soft ...

Abstract

The invention provides a light-weight self-lubricating wear-resistant joint bearing and a preparation method thereof, and belongs to the field of design and manufacturing of joint bearings. An inner ring and an outer ring of the joint bearing adopt titanium alloys as a substrate material; firstly, a TiN transition layer, a hard coating and a soft coating are deposited on an outer spherical substrate of the inner ring in sequence; then, a TiN transition layer and a hard coating are deposited on an inner spherical substrate of the outer ring in sequence; a micro pit texture is machined on an inner spherical surface of the outer ring by using a laser heat effect; and a solid lubricant is filled in the micro pit texture. The light-weight self-lubricating wear-resistant joint bearing can satisfy the performance requirements of light weight, wear resistance and self lubrication of the joint bearing in such special working condition fields as aviation and spaceflight.

Description

technical field [0001] The invention relates to the field of design and manufacture of joint bearings, in particular to a lightweight self-lubricating wear-resistant joint bearing and a preparation method thereof. Background technique [0002] As a high-performance material commonly used in industry, titanium alloy is widely used in various industrial fields, especially in the aerospace field, because of its advantages such as light weight, high specific strength, good corrosion resistance, and wide temperature range. With the development of production technology, in order to apply titanium alloy to more industrial technology fields, the protection of its surface is particularly important. Joint bearings are widely used in aviation equipment, and are widely used in important systems such as aircraft power systems, transmission systems, control systems, and executive systems. Due to the harsh service environment of aviation joint bearings, the requirements for life and relia...
