Introduction of cobalt-based alloy
Heat treatmentThe size and distribution of carbide particles and grain size in cobalt-based alloys are very sensitive to the casting process. In order to achieve the required endurance strength and thermal fatigue performance of cast cob...Views -
Introduction of cobalt-based alloy
PerformanceGenerally, cobalt-based superalloys lack coherent strengthening phases. Although the strength at medium temperature is low (only 50-75% of nickel-based alloys), they have higher strength, good thermal fatigue resistance and th...Views -
Introduction of cobalt-based alloy
Cobalt-based alloy is a cemented carbide that can withstand various types of wear, corrosion and high-temperature oxidation. It is commonly referred to as cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy (Stellite alloy was ...Views -
