spheroidization การใช้

• Spheroidization of silica powders in a radio frequency plasma
• Spheroidization evaluation standard of 12cr1mov steel used in power plant
• And the relationship between spheroidization efficiency and apparent density was also discussed
• The effect of feed rate and particle size on spheroidization efficiency was studied
• The results indicated that low graphite spheroidization rate and free cementite were the main causes of poor mechanical property
• Excessive imperfections even sub - grained boundaries may be introduced in cementite . this makes the accelerating dissolution and spheroidization of cementite easy . 5
• The fracture and spheroidization of cementite shows obvious anisotropy . there are two possible mechanism about spheroidization of cementite : the fracture cementite lamellae grows up non - uniformly and the fine spherical cementite particles grows up as the core
• Liquid penetrant testing , eddy current testing and magnetic particle testing are mainly used in the detection of surface flaws and near - surface flaws , radiographic testing and ultrasonic testing are mainly used in the detection of inner defects , ultrasonic testing is also used in the detection of spheroidization quality of smooth surface castings , while vibration testing is used in the detection of spheroidization quality of rough surface castings
