<p>Stainless steel sheet coating for at least one of the side comprises a metal (oxy)hydroxide barrier layer of 5-1000 nm in thickness; a titanium oxide porous layer of 5-1000 nm in thickness; and optionally a silicon (oxy)hydroxide upper layer of 5-1000 nm in thickness. The titanium oxide layer has a root mean square (RMS) roughness of 0.5-50 nm and porosity at 10-50 vol.% with a pore size of 0.5-100 nm. Stainless steel coating sheet for at least one of the side comprises a metal (oxy)hydroxide barrier layer of formula MO x or metal(oxy)nitride of formula NM x, of 5-1000 nm in thickness; a titanium oxide porous layer of formula TiO x, of 5-1000 nm in thickness; and optionally an upper silicon (oxy)hydroxide layer of formula SiO x, of 5-1000 nm in thickness. The TiO x layer has a root mean square (RMS) roughness of 0.5-50 nm, porosity of 10-50 vol.% and a pore size of 0.5-100 nm. Independent claims are included for: (1) a process of preparing the coated stainless steel sheet depositing the barrier layer on one of the side followed by depositing the TiO x layer in sol-gel form and the TiO x layer on the layered side of the steel, successively; and (2) an equipment for the food industry and a panel for building obtained from the coated stainless steel sheet. M : metal, preferably Si, Al or tin; Ti : titanium; Si : silicon; O : oxide; and x : not defined.</p> |
