Industrial Coatings Are Not Just About Corrosion Protection
By Expert Guest Author: Bill Naschak Industrial coatings comprise epoxy, phenolic, silicone, and urethane, but increasing demands for performance have ushered in new materials and process advancements in the industrial coatings marketplace. Surfaces subject to abrasive or erosive wear, extreme heat, corrosion, or require dimensional restoration or electrical insulation, as examples, can benefit greatly from high velocity oxygen fuel (HVOF) type coatings. Developed in the 1980's, this branch of thermal spray coatings brings surface property enhancements that can include: adhesive strength, hardness, and resistance to abrasion or permeation, using a wide range of alloyed metals and ceramic powders transformed into a plasticized state while fed through a high temperature gas stream. Also referred to as "wire flame spray" or the "combustion wire coating process", the process utilizes an oxygen-fuel gas flame for the heat source. Both wire form and solid rod...
