THERMAL BARRIER COATING

An electron beam vapor deposition process for depositing coatings comprises placing a source coating material in a crucible of a vapor deposition apparatus having a coating chamber; pressurizing said coating chamber from about 0.5 microbar to about 40 microbar; heating a work piece surface to a temp...

Beschreibung
Zusammenfassung:	An electron beam vapor deposition process for depositing coatings comprises placing a source coating material in a crucible of a vapor deposition apparatus having a coating chamber; pressurizing said coating chamber from about 0.5 microbar to about 40 microbar; heating a work piece surface to a temperature of from 1800 degrees Fahrenheit to 2000 degrees Fahrenheit; energizing said source coating with an electron beam that delivers a power density to the material in the crucible forming a vapor cloud from said source coating material; and depositing said source coating material onto a surface of a work piece.
