Hardfacing Arc Spray Wires

These hardfacing wire coating materials are similar to that of the machine element materials because they can be applied by arc spray and have hard and wear resistant characteristics. While the machine element materials have long been used for reclaiming worn down areas on shafts these hard surfacing materials are typically used in “as-sprayed condition”. This means they are sprayed onto a substrate and put into service without any further work or finishing, this is perfect for sliding wear and abrasion.

Hard surfacing or engineered coatings work in a number of key areas to include but not limited to;

• Abrasion resistance
• Corrosion resistance
• Wear resistance
• Hot ash resistance
• Oxidation
• Sulfidation
• High temperatures
• Cavitation

Note: Although arc spray coatings are diverse in their use, some applications are not suitable. Examples of an area not suitable would be in a direct impact situation such as the end of a jackhammer or the point of the teeth on an excavator bucket.

High production arc spraying saves time and money versus cladding or welding. Arc spray wires are dynamic, which means they can be applied thick and quick resulting in less time and labor expense. Arc spray only uses electricity and compressed air which also reduces the cost to apply such coatings.

In addition to the efficiency and cost savings of high production arc spray, it is a cool process and therefore does not distort parts or affect the heat treatment of a component and leads to endless favorable coating solutions.
