[0002] The novel tungsten wire surface copper zinc and molybdenum disulfide particle composite plating is an innovative surface treatment technology, aiming at improving the comprehensive performance of tungsten wire. Tungsten wire has a wide range of applications in many fields due to its high melting point, high strength and good electrical conductivity.
