Development of Cast Cobalt Alloy for SRP Valve Pairs

Abstract:

The work is devoted to studying of possibility to manufacture cast ball valves of sucker rod oil pumps instead of those manufactured by the powder metallurgy method from Stellite 20 alloy. It is shown that Stellite 20 cast alloy includes about 20% μ and σ brittle phases, destruction whereof, in case of impact-abrasion wear, when excavating oil, leads to quick failure of the valve pair. A new cast cobalt alloy not containing brittle phases has been developed instead of Stellite 20 alloy, which allowed to improve wear resistance of cast valve pairs to the level of valves produced by the powder metallurgy method.
