摘要： A tubular engagement interface for interfacing the coupling of two movably engaged tubulars is disclosed. The tubular engagement interface includes a body. The body includes a body engagement surface. A polycrystalline diamond element is coupled with the body, and includes a diamond engagement surface. The tubular engagement interface may be coupled with an inner wall of a first tubular, such that the body engagement surface, the diamond engagement surface, or combinations thereof are engaged with an opposing engagement surface of an outer wall of a second tubular. Alternatively, the tubular engagement interface may be coupled with the outer wall of the second tubular, such that the body engagement surface, the diamond engagement surface, or combinations thereof are engaged with an opposing engagement surface of the inner wall of the first tubular.
