Ball Valves with Nanostructured Titanium Dioxide Coatings for High-Pressure Acid-Leach (HPAL) Service download

F.W.Gartner has undertaken an aggressive coatings development effort to improve the protective quality of coatings and enhance the performance and extend the life of valves in severe HPAL conditions. In 2001, Mogas Industries, a partner in this initiative, qualified and applied a nanostructured titanium dioxide (n-TiO2) coating for gold and nickel/cobalt HPAL services.

Corrosion Performance of Laser Clad Overlays and Thermal Spray Coatings: A Comparison download

This paper includes the research used for a presentation given by F.W. Gartner at the joint TSS NACE Symposium in San Paulo, Brazil Nov. 8 - 10, 2010. This paper lays out the methodology and results of testing 316SS, Stellite® 6 and IN 625 in the laser clad and HVOF applied forms for corrosion resistance. The conclusion strongly supports laser cladding as the superior corrosion resistant process and shows that laser cladding produces coatings with similar corrosion resistance to wrought materials.

Kinetic Spray System Overview download

K.S.S. (Kinetic Spray System) is an advanced coating system that utilizes a high-pressure jet of heated gas or air to carry specifically sized engineering materials to the substrate at extreme velocities (mach 1-4) in their solid state. Because temperatures are kept low, these solid state materials maintain their original properties but may develop enhanced hardness due to impact, through a process similar to cold working. The coatings produced have near-zero porosity and oxides. They also have compressive residual stresses rather than tensile stresses, which means they can be built up to very high thicknesses with greatly reduced risk of delamination or spalling.
