Binder-Free Refractory Coating Formation with Improved Porosity Control
JHU REF: [C13071]
Invention novelty: Binder-free refractory coating formation process with improved porosity control for wear and corrosion protection of systems and devices.
Value Proposition: Refractory coatings are widely used in industrial applications to prevent wear and corrosion in systems and devices. Traditionally these coatings are deposited using spray techniques that facilitate metallizing large areas of diverse surfaces. Yet current spray techniques require the use of metallic binders to promote bonding between the spray material and the substrate and only allow for empirical porosity control in resultant deposits. Hence, inventors developed a novel process to form binder-free refractory coatings with improved porosity control, valuable as a method to increase the wear and corrosion resistance of refractory coatings for long-term environmental protection.
Advantages include:
- Binder-free refractory coating formation with improved porosity control
- Enables the formation of refractory coatings with increased wear and corrosion resistance for long-term environmental protection
- Simple two-step coating formation process translatable to industrial-scale components
Technical Details: Johns Hopkins researchers have discovered a simple two-step process for the formation of binder-free refractory coatings with improved porosity control for use in wear and corrosion protection of industrial systems and devices. A composite coating precursor is first applied to a substrate using any currently known deposition technique such as thermal spray. Next, the composite coating precursor undergoes a high-temperature reaction with carefully selected gaseous reactants to form the desired refractory coating. Unlike current spray techniques this method avoids the need for metallic binders and facilitates controlling the porosity of resultant refractory coatings through compositional manipulation of composite coating precursors, as opposed to the variation of spray process parameters. Hence, this invention presents a novel process which implements existing coating formation technologies to form binder-free refractory coatings with improved porosity control.
Looking for Partners: To develop and commercialize the invention as a novel process for the formation of binder-free refractory coatings.
