## Abstract Aseptic loosening of the artificial hip joint with osteolysis due to the wear particles from polyethylene cup has remained as a serious issue. To reduce this wear and develop a novel artificial hip joint system, we produced a superlubricious metal‐bearing material: for this, we grafted a 2‐methacryloyloxyethyl phosphorylcholine (MPC) polymer onto the surface of a cobalt–chromium–molybdenum (Co‐Cr‐Mo) alloy. For ensuring long‐term benefit retention of poly(MPC) on the Co‐Cr‐Mo alloy for application as a novel artificial hip joint system, several issues must be considered: strong bonding between poly(MPC) and Co‐Cr‐Mo surface, high mobility of free end groups of the poly(MPC) layer, and high density of the introduced poly(MPC). Considering these issues, we introduced a 3‐methacryloxypropyl trimethoxysilane (MPSi) intermediate layer and a photoinduced graft polymerization technique to create a strong covalent bond between the Co‐Cr‐Mo substrate and the poly(MPC) chain via the MPSi layer. The thickness and density of the poly(MPC) layer on the surface increased with the MPC concentration and photoirradiation time. The grafted poly(MPC) layer successfully provided super‐lubr
