Fixtures for Masking Metal Parts

An assembly prepared for a surface coating process, comprising:

• a femoral component having an articular side, a bone facing side, and a peripheral edge defining an intersection between the articular side and bone facing side, the bone facing side having a first planar surface having a first perimeter and a second planar surface having a second perimeter, the perimeters of the first and second planar surfaces defining at least a portion of a peripheral edge of the femoral component;
• and
• a fixture having a first panel and a second panel connected to the first panel, the first panel having a first interface surface defining a first perimeter of the first panel, the first perimeter of the first panel having substantially the same shape as the first perimeter of the first planar surface of the femoral component, the second panel having a second interface surface defining a second perimeter of the second panel, the second perimeter of the second panel having substantially the same shape as the second perimeter of the second planar surface of the femoral component,
• wherein, when the fixture is mounted to the bone facing side of the femoral component, the first interface surface engages the first planar surface of the femoral component and covers an entirety thereof, and the second interface surface engages the second planar surface of the femoral component and covers an entirety thereof.
