1. Introduction to Self-Fluxing Alloy Powders
Self-fluxing alloy powders are a class of metal powders engineered to promote metallurgical bonding and surface integrity during thermal spraying processes, such as flame spraying and plasma spraying. These powders are widely used in wear-resistant and corrosion-resistant coatings thanks to their ability to form a dense, adherent layer without the need for external fluxing agents.
Self-fluxing powders typically include elements such as:
- Nikel (Ni)
- Krom (Cr)
- Bor (B)
- Silisyum (Si)
- Demir (Fe)
These powders are prealloyed and engineered to melt and flow easily during spray deposition, offering excellent bonding and mechanical properties.
B2B Alıcıları için Neden Önemli?
For large-scale manufacturers in oil & gas, aerospace, mining, and power generation, sourcing high-performance coating materials like self-fluxing alloy powders is critical. These powders help extend the life of equipment and reduce maintenance costs, making them a strategic procurement priority.
2. Industrial Applications of Self-Fluxing Alloys
Self-fluxing alloy powders are widely used in industries where equipment and components are subject to extreme friction, temperature, and corrosion.
Common Industry Applications:
