▎ 摘　　要

NOVELTY - Inner fixing object comprises substrate with upper surface provided with ultrafine diamond graphene layer made of nanodiamond alkene layer having lamellar crystal structure, and titanium particles are provided between nanodiamond graphene layers. The nanodiamond graphene layer has thickness of less than 3 mu m. USE - Inner fixing object. ADVANTAGE - The inner fixing object has good performance, has long life, and is safe. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation inner fixing object by subjecting substrate by ultrasonic surface purification; plating substrate with nano diamond-ene-plated titanium particles via vacuum ion plating; performing composite plating; and performing surface treatment of subject having fixation layer.
