Abstract: The valve body and valve cup of mud pump are parts that are easily
to be worn end broken.In order to increase the life-time of these parts,
we studied the technology of increasing the life-time of valve body and
valve cup by ionic welding. On the basis of the results of laboratory and
field experiments the question is discussed on the technology of ionic bead
welding，and wear-resistant alloy for valve body and valve cup，and the
data of the experiments in oil fields are listed .The results of the experi-
menu indicate that the life-time of the valve body and valve cup can be
increased obviously by means of ionic welding.
