Abstract
An analysis is made of contact damage in brittle coatings on metal substrates, using a case study of a dental porcelain coating of thickness between 0.1 and 1 mm fused onto a Pd alloy base, with spherical indenter of radii 2.38 and 3.98 mm. At large coating thicknesses (>300 mu m), the first damage takes the form of surface-initiated transverse cone cracks outside the contact. At small coating thicknesses (
