If used in salt water mud, corrosion resistance of the conventional rotor less effective, lead to the mud motors failure in serious condition, also direct impact on the life of the mud motors.

Rotor coating:

Surface spray coating:

To adapt mud motor to a variety of drilling mud , but costs are high, the coating is 10 times than the normal, more saturated salt water mud conditions in use.

Thick rotor coating process:

Common technology on chrome-coating depending on the surface shape of the rotor creates large tolerance between actual streamline and the academic streamline of the rotor, which will reduce the efficiency of the power section. Special chroming coating technics by landrill will control the rate between apex and vale of the coating control to 1:3, Best of up to 1:1.
