The mechanism of protective layer formation on sintered metal surface
in corrosive media has been theoretically studied. (sic) sintered stee
l, which is used for the fabrication of working parts of immersion ele
ctric pumps, has been tested in stratal water containing 100 - 300 g/l
minerals and 7 - 130 mg/l H2S. An effective method of corrosion prote
ction of sintered steels has been suggested.
