Abstract: A pump is disclosed. The pump may include at least one pumping mechanism. The at least one pumping mechanism may include a barrel formed of a substrate having a bore and a plunger formed of a substrate and slidably disposed within the bore in the barrel. The pump may further include a coating disposed on the plunger. The coating may include a main layer containing a tribological material and a sacrificial break-in layer disposed on the main layer, the break-in layer containing a tribological material.

Abstract: An undercarriage track joint assembly includes a first link having a first bore at a first end and a second bore at a second, opposite end, and a second link having a first bore at a first end and a second bore at a second, opposite end. A pin may extend between the first and second links, positioned at least partially within the first bores of the first and second links, or partially within the second bores of the first and second links. A bushing may extend between the first and second links, a central axial bore being defined through the bushing. The pin may extend through the central axial bore through the bushing, the pin being coated with a diamond-like carbon (DLC) coating over at least a portion of an outer diameter surface of the pin, the coating providing a contact layer between the outer diameter surface of the pin and an inner diameter surface of the central axial bore through the bushing.
