AI Technical Summary
Existing sliders have deficiencies in wear resistance and corrosion resistance, especially in marine environments, which make it difficult to meet usage requirements. In addition, grease needs to be frequently applied, which is inconvenient to maintain.
A combination of hard coating and lubricating coating is applied on a metal substrate. The hard coating is WC or SiN, and the lubricating coating is MoS2 or polytetrafluoroethylene. The thickness is not less than 30 microns and 20 microns respectively, providing wear resistance and self-lubricating functions.
The wear resistance and corrosion resistance of the slider are improved, the frequency of grease application is reduced, and the convenience of use is improved.

Abstract
Description
Technical Field
[0001] This utility model relates to coating structures, specifically to a multi-functional coating structure for a slider. Background Technology
[0002] The slider is connected to the aircraft fuselage via mechanical connection or welding, and works with the launcher to form a rail-guided launch device. The slider coating should be wear-resistant, corrosion-resistant, and have a low coefficient of friction. Currently, sliders are mostly made of structural steel, which has poor corrosion resistance. They are usually nickel-plated and lubricated with grease before leaving the factory. However, their wear and corrosion resistance are insufficient to meet the requirements for use (especially the environmental adaptability requirements in marine environments). Moreover, the grease needs to be applied multiple times after delivery, making maintenance inconvenient. Summary of the Invention

[0016] Figure 1 In the middle, 1. Metal substrate, 2. Hard coating, 3. Lubricating coating. Detailed Implementation
[0017] For reference Figure 1 The multifunctional coating structure of the slider consists of a metal substrate 1, a hard coating 2, and a lubricating coating 3. The metal substrate 1 constitutes the main structure of the slider; the hard coating 2 is selected from WC or SiN coatings, with a thickness of not less than 30 micrometers, which can provide reliable wear resistance and corrosion resistance at the same time; the lubricating coating is selected from MoS2 coatings or polytetrafluoroethylene coatings, with a thickness of not less than 20 micrometers.
[0018] Coating application method: First, prepare the slider metal substrate 1 using machining or other methods, ensuring sufficient coating thickness is allowed. Then, prepare the hard coating 2 using methods such as flame spraying or laser spraying. Finally, spray a lubricating MoS2 coating 3. Depending on the actual usage and coating thickness, reapply the lubricating coating 3 (MoS2 coating or PTFE coating) after a certain number of friction cycles.
