Abstract

For the charge used in making iron–base sintered friction parts the following powders are employed: PZh–1, PZh–2, and PZh–3 iron powders (All–Union State Standard 9849–61) and PM–1, PM–2 copper powders (All–Union State Standard 4960–49). In the as–delivered state all these brands of powder contain a certain amount of bound oxygen in the form of oxide films and impurities. Under the All–Union State Standards mentioned above, the oxygen content in iron powders brand PZh–1 and PZh–2 should not exceed 0.5 and 1.0%, respectively, but no regulations are laid down with regard to PZh–3 or to the copper powders. As shown by mass analysis, the oxygen content in PZh–3 powder ranges from 1.1 to 1.7%, and in the copper powder from 0.1 to 0.2%.
