Festoon lamp holder

having a structure of an ionic bond or a covalent bond, high bond energy between atoms with strong, the surface free energy is low, thereby imparting a high melting point of the ceramic material, high stiffness, high chemical stability, high dielectric insulation capacity, thermal expansion coefficient is small, and a small coefficient of friction characteristics; Poor compared with the metal material, the plastic deformation capacity and the sensitivity of stress concentration and cracks. Obviously, as a mechanical structure with a ceramic material, its reliability differential than the metal material, machining is difficult, the cost is high.

However, the use of the thermal spraying technique, preparing a ceramic coating on a metal substrate, can the characteristics and the characteristics of the ceramic festoon lamp holder material of the metal material organically combined to obtain the composite material structure. This composite structure with exceptional performance, thermal spray technology applied to civilian industrial areas such as energy, transportation, metallurgy, textile, petrochemical, machinery quickly expanded from high tip.
