Combustion Flame Spray Coating: Traditional Thermal Spray Solutions

Combustion Flame Spray Coating, also known as traditional thermal spray coating, utilizes a combustible gas as a heat source to melt feedstock materials, which may be in the form of powder, wire, or rod. The molten droplets are then propelled onto the component surface, where they impact and form a protective coating. Due to the high temperatures involved, masking for flame spray coatings can be particularly challenging.

Flame spray coatings are widely used across various industries, including Aviation/Aerospace, Energy (such as Industrial Gas Turbines), Semiconductors (Parts Cleaning), and General Industrial applications. These coatings are ideal for applications requiring abradable coatings, wear resistance, and corrosion protection.

Recommended Products for Combustion Flame Spray

– 6605-07D: A basic single-sided glass cloth tape, ideal for non-critical abrasive blasting masking. It’s a reliable option for single-layer secondary masking.

– 6615-07: A double-sided fiberglass tape, 7 mil thick, featuring silicone adhesive on both sides and a crepe paper liner. This tape offers excellent conformability and strong adhesion to metal, making it perfect for face-to-back masking.

– 6615-12: A thicker, 12 mil double-sided fiberglass tape, ideal for single-layer plasma spray masking.

– 6625-11: An aluminum foil flame spray masking tape, 11 mil thick with a 4 mil foil layer, providing robust protection.

– 6525-08: An all-purpose abrasive blasting masking tape, suitable for both grit blasting and air plasma applications. This tape is constructed with silicone rubber-coated fiberglass and features a silicone adhesive.

– 6525-16: A double-layered masking tape that allows for single-layer application, reducing masking time by 50% in situations where two layers of standard tape would be required.

– 7422W: A heavy silicone-coated fiberglass fabric designed for demanding jobs that require protection of large surfaces. This fabric is more abrasive-resistant and is well-suited for both primary and secondary masking tasks.

Masking Compounds

– TacMold (A2023-A / A2023-B): A two-part silicone putty designed to withstand all forms of thermal spray, including GF-HVOF and LF-HVOF. TacMold is ideal for masking holes or intricate profiles and is reusable in some cases.

– TacBloc: A soft, conformable, putty-like material designed for masking holes, grooves, key slots, or other unique configurations. Unlike TacMold, TacBloc adheres directly to metal, making it ideal for areas where anchorage is difficult. TacBloc is suitable for all types of thermal spray.
