1. A process for extending the cyclic service life of a thermal barrier coating made of chemical thermal barrier coating composition, which has been applied to a substrate with an oxidizing bond coat in between, the thermal barrier coating includes microcracks, which are bridged by punctiform contact locations, the process comprising:
improving a strain tolerance of the thermal barrier coating by weakening the punctiform contact locations in the thermal barrier coating.
2-9. (canceled)
10. The process as recited in claim 1, wherein the weakening of the microcontacts includes performing a shot-peening process.
11. The process as recited in claim 1, wherein the weakening of the microcontacts includes performing a Trowal process.
12. The process as recited in claim 1, wherein the weakening of the microcontacts includes an infiltration process using an infiltration medium, followed by a heat treatment, wherein the infiltration medium undergoes a volumetric expansion during a liquid-solid phase change.
13. The process as recited in claim 12, wherein the infiltration medium is water, further comprising introducing the water introduced into pores in the thermal barrier coating by at least one of immersion, spraying and via the is phase and briefly freezing the water using liquid nitrogen or dry ice, and subsequently removing the infiltration agent by one of standard drying and vacuum drying.
14. The process as claimed in claim 12, further comprising restricting a penetration depth of the infiltration medium to an outer region of the thermal barrier coating using suitable process parameters so as to avoid having a negative effect on the adhesion of the thermal barrier coating.
15. The process as recited in claim 13, wherein a spatial propagation of the brief freezing step is controlled by targeted dissipation of heat into the component interior, so that a solidification front, starting from an interface of the thermal barrier coating, is guided in a direction of the surface of the thermal barrier coating instead of prematurely closing off the porosity from the outside before the solidification has ended so as to avoid having a negative effect on the adhesion of the thermal barrier coating.
