hardfacing alloys at a glance hardfacing alloys stellite alloys deloro alloys the cobalt-based stellite™ alloys are our most wellknown and successful alloys with the best “all-round” properties they combine excellent mechanical wear resistance especially at high temperatures with very good corrosion resistance the stellite™ alloys are mostly cobalt based with additions of cr c w and/or mo they are resistant to cavitation corrosion erosion abrasion and galling the lower carbon alloys are generally recommended for cavitation sliding wear or moderate galling the higher carbon alloys are usually selected for abrasion severe galling or lowangle erosion stellite™ 6 is our most popular alloy as it provides a good balance of all of these properties the stellite™ alloys retain their properties at high temperatures where they also have excellent oxidation resistance they are typically used in the temperature range 315 – 600° c 600 – 1112°

hardfacing alloys pta laser weld deposition plasma transferred arc pta weld deposition the pta process is easily automated providing a high degree of reproducibility of the weld overlays in addition because of the highly concentrated heat source this process benefits from high powder utilization and can achieve a very low level of iron dilution in the overlay tungsten electrode because the hardfacing materials are in powder form it is possible to produce overlays from many different materials and combinations of materials with a wide range of hardness and other properties plasma gas nozzle powder nozzle shielding gas nozzle water cooling powder shielding gas arc we manufacture fit-for-purpose pta equipment packages please see contact information on page 25 for any questions or requests 10

hardfacing alloys plasma spray hvof deposition plasma spraying in the plasma spraying process powder is softened or melted in the plasma gas stream which also transfers the particles to the workpiece the plasma arc is not transferred to the workpiece it is contained within the plasma torch between an axial electrode and a water-cooled nozzle the process is operated in normal atmosphere in a shielding gas stream e.g argon in a vacuum or under water due to the high temperature of the plasma gas stream the plasma spray process is especially suitable for spraying high melting-point metals as well as their oxides powder delivery plasma gas delivery powder flame electrode water cooling 14
