Abstract (en)
A process of providing a thermal barrier coating on a metal substrate comprises the steps of: a) applying a metallurgical bondcoat (12) to the substrate (10); b) depositing a first zirconia layer (14) on the bondcoat (12); c) depositing a second zirconia layer (16) on the first zirconia layer (12); and d) controlling substrate temperature during steps b) and c) to provide the first zirconia layer (14) with substantially zero porosity and to provide the second zirconia layer (16) with between about 10% and 20% porosity. A product produced by the process is also disclosed. <IMAGE>
