Spray Coating Components Manufacturers

How to optimize spray coating components to improve wear and corrosion resistance?

Jiaxing Shengbang Mechanical Equipment Co., Ltd. is a comprehensive technology enterprise integrating R&D, production, sales and maintenance of key components and textile machinery equipment, and is also committed to the research and development of new materials and fabrics. The company has management, R&D, sales, trade and production departments, of which the production department covers machining, maintenance, plasma spraying (Plasma Coating) and special yarn spinning workshops. In addition, the company has branches in Shanghai and Nantong: Shanghai Panguhai Technology Engineering Co., Ltd. (sales and R&D headquarters) and Haian Jingtong New Materials Technology Co., Ltd. (production and testing base for machinery and yarn).

1. Material selection: high-performance coatings adapt to different industrial needs
Jiaxing Shengbang Mechanical Equipment Co., Ltd. relies on new material R&D capabilities to recommend the best coating materials for different application scenarios:

Wear-resistant coating:
Tungsten carbide (WC-Co), chromium carbide (Cr3C2-NiCr)-suitable for high-wear parts of textile machinery (such as yarn guides, rollers).
Alumina (Al2O3) - used for wear protection in high temperature environments.

Corrosion-resistant coating:
Nickel-based alloy (Inconel 625) - anti-corrosion for chemical equipment.
Zinc-aluminum coating (Zn-Al) - replaces traditional galvanizing and is used for long-term anti-corrosion of steel structures.

2. Spraying process optimization: plasma spraying and quality control
The production department of Jiaxing Shengbang Mechanical Equipment Co., Ltd. is equipped with a **plasma spraying (APS)** workshop to improve coating performance through the following process control:

Precise parameter control:
Spraying distance, powder feeding rate, and gas ratio optimization to ensure low porosity of the coating (<2%).

Special process applications:
HVOF outsourcing cooperation: for ultra-high hardness requirements (such as WC-Co coating).

Cold spraying technology: used for low-temperature spraying of sensitive substrates (such as aluminum alloy textile machinery parts).

3. Surface pretreatment and post-treatment: Strict process to ensure bonding strength
Pretreatment:
Sandblasting + chemical cleaning: Use Al2O3 sandblasting (Ra≥5μm) to ensure coating bonding strength>50MPa.

Post-treatment:
Sealing treatment: Use epoxy resin to penetrate and significantly improve corrosion resistance (salt spray test>1000 hours).
Laser remelting: Cooperate with Shanghai R&D headquarters to perform laser post-treatment on high-precision parts to reduce micro cracks.

4. Quality inspection: Full process performance verification
The company ensures coating reliability through strict inspection:
Wear resistance: Taber wear test (ASTM D4060), reciprocating friction test.
Corrosion resistance: Salt spray test (ASTM B117), electrochemical analysis.
Microscopic inspection: SEM/EDS analyzes coating composition and porosity.
