Thermisches Spritzverfahren und Vorrichtung zum Durchführen des Verfahrens

摘要

A high velocity oxygen fuel (HVOF) thermal spray assembly (S) applies a protective coating of e.g. MCrAIX to a workpiece e.g. gas turbine engine blade as it rotates about an axis (A). The spray jet (S) directed at an angle to the axis of rotation and varies during the spray application procedure by part alteration of the axis of rotation (A). The change in axis of rotation (A) is synchronized with the shift in angle of spray (S) discharge. The axis of rotation (A) varies between 0[deg] and 30[deg] and passes through the work piece. The assembly has a work piece holder (17) that rotates about an axis (A), a spray jet (7), a swivel-action motion driver (29), and a movable spray jet (7). Also claimed is a commensurate process.
