A coated part is exposed to a gas flow. The gas flow has a characteristic gas flow direction distribution over a surface of the coated part. The coated part has a substrate having a substrate surface and a coating over the substrate surface. The coating comprises at least one coating layer. A first such layer is columnar and has a column boundary direction distribution. The column boundary direction distribution is selected for partial local alignment with the gas flow direction distribution.

Thermal barrier coatings and methods of application

A ceramic material is applied to a part. The part is placed in a deposition chamber and a first electric potential is applied to the part. Components are evaporated for forming the material. The evaporated components are ionized. The first electric potential is modulated so as to draw the ionized component to the part. The modulation comprises maintaining at least an ion current density in a range of 2-1000 mA/cm.

Ceramic coating deposition

A material is applied to a part. The part is placed in a deposition chamber and a first electric potential is applied to the part. Components are evaporated for forming the material. The evaporated components are ionized. The first electric potential is modulated so as to draw the ionized component to the part. The modulation comprises a plurality of first steps for PA-PVD. Each of the first steps comprises a series of pulses of negative potential. The modulation further comprises a plurality of second steps for PVD alternating with the first steps.
