The coating has particles having a mean size of less than 100 nm and has more than 95% by mass of AlOand/or ZrO, referred to as “protective particles.” The protective particles cover more than 50% and less than 90%of the protected zone, as percentage by surface area. The process includes the step of subjecting the heat-resistant product to a temperature of greater than 600° C. for a duration of greater than 0.5 hours.
