Abstract

En fremgangsmåte til dannelse av et tett og sprekkfritt hematittinneholdende beskyttende lag på et metallbasert substrat til bruk i et oksiderende og/eller korrosivt miljø med høy temperatur omfatter påføring på substratet av en partikkelblanding bestående av: 60 til 99 vekt%, særlig 70 til 95 vekt%, så som 75 til 85 vekt%, av hematitt med eller uten jernmetall og/eller ferrooksid; 1 til 25 vekt%, særlig 5 til 20 vekt%, så som 8 til 15 vekt%, av nitrid- og/eller karbidpartikler, så som bornitrid-, aluminiumnitrid- eller zirkoniumkarbidpartikler; og 0 til 15 vekt%, særlig 5 til 15 vekt%, av én eller flere ytterligere bestanddeler som består av minst ett metall eller metalloksid eller en varmekonvertibel forløper for disse. Hematittpartiklene blir deretter sintret ved varmebehandling av partikkelblandingen, for å danne det beskyttende lag som består av en mikroporøs sintret hematittmatriks hvor nitrid og/eller karbidpartiklene er innkapslet, og som, under tilstedeværelse, inneholder den ene eller de flere ytterligere bestanddeler. De mekaniske, elektriske og elektrokjemiske egenskaper til det beskyttende lag kan forbedres ved bruk av et oksid av titan, sink, zirkonium eller kobber. Det beskyttede substrat kan typisk brukes i en celle for elektrolytisk utvinning av et metall, så som aluminium.
