Abstract Scope |
Thermal barrier ceramic coatings are typically deposited using expensive equipment such as plasma spray or EBPVD. This presentation will address a novel, easy-to-apply TBC coating based on a patented aluminophosphate material. The coating incorporates a novel ceramic microballoon additive in pre-ceramic polymer slurry formulations for low thermal conductivity and sprayed onto metal or ceramic substrates with conventional HVLP spray equipment while achieving ceramic conversion below 300 °C. These coatings are deposited directly on metal substrates with excellent adhesion without needing a primer or bondcoat pretreatment. These coatings exhibit ultra-low thermal conductivity (< 0.5 W/m*K at 25 °C) and are suitable for large-scale industrial applications. Experimental efforts to assess performance on various metal substrates and under thermal shock, wear, and corrosive environments with related material characterization results will be discussed. |
