There are several options available in the realm of surface treatment. Some metal parts and equipment are subjected to a greater degree of rough wear and corrosion. In this case, hard facing can be a practical solution. It is most popular for its ability to restore surfaces that have been worn from strenuous use.
Whether you decide to tackle the job alone or outsource the project to industry professionals, it is prudent to do a bit of homework. Make sure the equipment is reliable and meets modern safety, environmental and workability standards. When researching hard facing solutions:
1. Explore the art of hard facing through welding.
2. Outsource the task to reputable hard facing service companies.
3. Try thermal spray hard facing as an effective alternative.
Action Steps
The best contacts and resources to help you get it done
Buy state-of-the-art welding hard facing equipment
Welding is the preferred method for hard face coating on metal surfaces and equipment. The process is recommended for any metal parts that are subject to continual wear and tear or are prone to corrosion. It can be used to protect new equipment or to restore worn surfaces on old equipment.
I recommend: Deloro Stellite has hard facing information as well as a high-tech inventory of welding hard facing equipment, including control units, torches and rotary positioners. Also available is a selection of hard-facing alloys.

Find hard facing services for industrial equipment
Many surface treatment companies offer hard facing services. Providers of hard facing service typically have elaborate setups for the complex machinery required for this coating process. Service providers should be ready with process and material information with access to sales representatives and engineers.
I recommend: Industrial Hardfacing, Inc. has been in service for more than 30 years. They offer door-to-door pick up and deliver most projects within 30 days.
A&A Company offers Plasma Transferred Arc (PTA) hard facing services. Their surface coatings are ideal for metal equipment that is prone to corrosion or rough wear.
Consider thermal spraying as a hard facing technique
Thermal spray coating is yet another method for hard facing metal surfaces and equipment. The process involves a mix containing alloy powders that are heated to extreme temperatures and applied to metal surfaces.
I recommend: Saint-Gobain coating solutions offers an inventory of thermal spray equipment. Wires, metallic powders and plasma spray equipment are all available for hard facing coat needs. Spraying equipment and hard facing services alike are available at
Sulzer Metco. Weld hardfacing equipment can also be purchased here.
