F.W. Gartner is a global provider of high quality, advanced surface engineering solutions.
Thermal spraying is a process in which metallic and non-metallic materials are deposited in a molten or semi-molten form on a prepared substrate, imparting properties that the substrate would not otherwise possess.
The laser cladding process is essentially a welding process utilizing an infinitely controllable laser beam as its heat source. This technology allows for complete metallurgical bonding with minimal HAZ (heat affected zone) and dilution, along with a reduction in other undesirable side effects such as oxidation and decarburization.
Machining and grinding are offered as a supplementary service to thermal spraying in order to minimize downtime and eliminate duplication of efforts. Many of our machines are very large for their type as detailed on the linked list.
CNC is the preferred process for repetitious machining and milling when absolute accuracy is required. It is also useful for manufacture of complex shapes from samples by integration with our CMM and CAD/CAM software.
To ensure that the coatings and cladding we provide meet the highest standards, we have a comprehensive testing lab on the premises that is permanently staffed. ASTM compliant and custom reports are produced to client requirements.
Our range of sealants and surface coatings primarily seal the low-level porosity (as little as 0.1%), that can compromise the corrosion performance of even the best coatings. Each sealant can have additional characteristics such as being non-wetting to molten metals, improving wetting, reducing friction or improving fiber release.
F. W. Gartner complies with all requirements for ISO 9001/2008. Various internal, O.E.M. and customer-specified process and procedure protocols are also strictly adhered to.
At F.W. Gartner we pride ourselves on having been leaders of process and materials development in the thermal spray and surface engineering fields since their inception. Keeping pace with emerging technologies is an integral component in the growth of our business.
Plasma transferred arc (PTA) hardfacing is a versatile method of depositing high-quality metallurgically fused deposits on relatively low cost surfaces. Soft alloys, medium and high hardness materials, and carbide composites can be deposited on a variety of substrates to achieve diverse properties including wear and corrosion resistance at ambient or elevated temperatures.
After a high quality coating is applied, ball valve components must be ground and mate lapped to provide a gas tight seal across a range of operating pressure and temperature regimes. Our finishing technology is capable of consistently meeting or exceeding any customer requirement, across a range of coatings and sizes.
