Hard-facing is a metal-forming process that uses a hard, wear-resistant material to create a surface layer on a base metal material. This process enhances surface durability and wear resistance, providing resistance to abrasiveness while increasing service life on components that are subject to extreme working conditions.
Key Features:
- Surface Coating Process: This is a hard alloy that is deposited on a metallic surface through methods of welding, thermal spraying, and laser cladding.
- Wear Resistance: This offers an added layer of protection against abrasion, impact, erosion, corrosion, and metal-to-metal wear.
- Cost-Effective Restoration: Instead of simply replacing components, worn areas can be rebuilt and reused using hard-facing.
Hard-facing is ideal for use in industries such as mining, agriculture, construction, oil & gas, and manufacturing, where equipment is frequently dealing with abrasive material or high-impact applications. There is a wide variety of hard-facing materials available, including chromium carbide, tungsten carbide, iron-based alloys, etc. Elements such as crusher jaws, drill bits, valves, conveyor screws, etc. are excellent candidates for hard-facing. The method used and qualified material are chosen based on the type of wear (from experience) and the base material properties.
