Superior Wear and Abrasion Resistance

With a typical hardness of approximately 1800-2200 HV, GREENSTONE wear-resistant ceramic composite powder is designed to produce extremely hard protective surfaces capable of resisting severe abrasion, erosion and particle impact.

This makes it particularly suitable for components such as:

• Mining chutes and hoppers
• خطوط لوله صنعتی
• اجزای دیگ بخار
• تجهیزات جمع‌آوری گرد و غبار
• اجزای پمپ و شیر
• اجزای مرتبط با توربین
• High-wear mechanical surfaces

عملکرد در دمای بالا

The ceramic material system provides excellent thermal stability, with a typical maximum continuous operating temperature of approximately 1200 ° C and short-term temperature resistance up to approximately 1600 ° C, depending on the exact composition, coating structure and service conditions.

This enables protective coatings for components exposed to elevated temperatures and repeated thermal cycling.

مقاومت در برابر خوردگی عالی

The ceramic-based coating system provides resistance to a broad range of corrosive industrial environments.

According to the supplied technical data, representative coatings can meet ASTM G31 corrosion testing requirements, with salt-spray performance reported up to approximately ساعت 500 under the applicable test conditions.

Actual corrosion performance depends on coating composition, porosity, thickness, substrate preparation and operating environment.

Lightweight Ceramic Protection

With a typical density of approximately 3.8-4.2 g/cm³, the ceramic composite system is significantly lighter than many conventional metallic wear-resistant coating materials.

This provides an advantage for applications where both surface protection and component weight are important, including aerospace and rotating equipment.

HVOF Thermal Spray Applications

The powder can be engineered for High-Velocity Oxygen Fuel (HVOF) thermal spraying, producing dense wear-resistant protective coatings on suitable substrates.

برنامه های معمولی شامل:

تولید برق: Boiler tubes, industrial piping and high-wear surfaces.

Petrochemical & Oil and Gas: Corrosion- and erosion-resistant surfaces for valves, pipelines and process equipment.

ماشین آلات صنعتی: Wear-resistant surfaces for components subjected to continuous abrasion.

Plasma Spray Applications

GREENSTONE ceramic composite powder is suitable for compatible اسپری پلاسما systems where high hardness, thermal stability and ceramic coating performance are required.

Properly optimized plasma-sprayed coatings can provide high bond strength and dense protective surfaces on complex component geometries.

Laser Cladding Applications

Selected ceramic-metal composite formulations can be integrated into روکش لیزری processes to manufacture metallurgically bonded wear-resistant composite layers.

Typical applications include turbine-related components, molds, industrial tooling and severely worn mechanical parts requiring localized surface reinforcement.

Because pure ceramics and ceramic-rich materials behave differently from conventional metallic laser-cladding powders, the exact composition, binder/metallic phase and laser parameters should be selected according to the substrate and required coating properties.

Cold Spray and Low-Temperature Processing

Compatible formulations can also be developed for اسپری سرد and other lower-temperature deposition processes where minimizing thermal influence on the substrate is important.

This can be beneficial for precision components and applications where substrate distortion or thermal degradation must be minimized.

مقاومت در برابر شوک حرارتی عالی

A typical thermal expansion coefficient of approximately ۱۶–۱۷ × ۱۰⁻⁶/کلوین provides relatively good compatibility with selected metallic substrates and helps reduce thermal stress when the coating system is properly engineered.

High Coating Bond Strength

For optimized plasma-sprayed coating systems, typical bond strength can exceed approximately 50 مگاپاسکال, depending on substrate preparation, coating composition and spraying parameters.

Custom Ceramic Powder Solutions

GREENSTONE can provide customized ceramic and ceramic-metal composite powder solutions based on:

توزیع اندازه ذرات
Ceramic composition
Metallic binder system
Deposition process
مواد بستر
سختی مورد نیاز
دمای عملیاتی
Wear and corrosion environment

This allows the powder system to be optimized for specific industrial coating and surface-engineering applications rather than using a single formulation for every process.
