A CERMET is:
A{'text': 'A thermoplastic', 'label': 'D'}
B{'text': 'A ceramic with metal coating', 'label': 'A'}
C{'text': 'A composite of ceramic particles embedded in a metal matrix — combining ceramic hardness with metal toughness', 'label': 'B'}
D{'text': 'A pure ceramic with high melting point', 'label': 'C'}
Answer & Solution
Correct answer: C. {'text': 'A composite of ceramic particles embedded in a metal matrix — combining ceramic hardness with metal toughness', 'label': 'B'}
Cermet = CERamic + METal. Carbide tools (WC particles in Co matrix) are the canonical example. Hardness comes from the ceramic phase; the metal binder provides toughness against fracture.
