Inotec Coatings and Hydraulics Inc. has expertise in thermal spraying, High Velocity Oxygen Fuel (HVOF), which involves introducing various powders into a flame and expelling them at a high velocity. This allows the application of coatings that are very low in porosity and very high in bond strength. Other recent additions to Inotec include Plasma Transferred Arc Welding (PTAW) units to further Inotec’s ongoing focus toward complete automation for improvement of product quality and consistency. And Inotec’s shot-peening conforms to each Customer’s specific standard, as controlled by their specifications and Inotec’s laboratory.

HVOF - High Velocity Oxygen Fuel
HVOF (High Velocity Oxygen Fuel) coatings are applied at velocities that surpass 600 m/sec. Inotec technicians can apply a number of different coatings, from stainless steel to tungsten carbide, nickel chrome to copper. All of these coatings can be applied at Inotec’s facility or on-site to best meet Customer requirements.
PTAW - Plasma Transferred Arc
| PTAW (Plasma Transferred Arc) is focused on customer demands for services such as impact-resistant tungsten carbide overlay with multi-pass capabilities. Plasma transferred arc is a high energy, inert gas welding process that produces very high quality dense deposits with minimal dilution and deformation to the base material. PTAW is applied with a high energy density similar to electron beam and laser welding, and is used to apply precise overlays on parts subject to corrosion, thermal shock, severe abrasion, or slurry erosion. The technical advantages of PTAW begin with its metallurgical / low dilution bond, 2 - 5% on average. PTAW is applied with a low heat input, providing minimal distortion and high resistance to chipping because is its very dense metallurgical structure. PTAW production rates are high compared to traditional welding processes. |

Currently, the PTAW division has the capability of overlaying OD’s and ID’s with numerous hardfacing alloys as well as corrosion-resistant materials. A Customer can choose to apply many materials, including Tungsten Carbide and high nickel alloys, etc., to numerous components. Applications are: crusher teeth, screens, all ground engagement equipment for the oilsands market, valve components, down hole tools, etc.
