СОСТАВ МАТЕРИАЛОВ ДЛЯ ПРИГОТОВЛЕНИЯ УПРОЧНЯЮЩИХ ПАСТ

摘要

FIELD: chemistry. ^ SUBSTANCE: proposed paste contains non-equilibrium content alloy powder with excess metal, capable of diffusion hardening and thermal reaction when heated with gallium. Gallium, saturated with nitrogen at pressure of not less than 5 MPa and temperature equal to melting point of gallium, is used in the paste. Minimum weight content of gallium is between 30% and 60%. Diffusion hardening temperature of the paste lies between 29.7C and 700C and the time interval lies between 2 and 8 hours. ^ EFFECT: increased strength of the paste. ^ 3 ex
