NOVELTY - Preparing porous graphene enhanced titanium-based nanometer composite material based on laser sintering involves mixing hydrogenated titanium powder, titanium powder and graphene powder together by a certain percentage and placing in a ball mill and adding argon in intermittent in ball mill and mixing to obtain a composite powder. Laser array or line array sintering is performed using laser sintering technology in the composite powders sintered dehydrogenation and hydrogenation of titanium and titanium and graphene sintered body. USE - Method for preparing porous graphene enhanced titanium-based nanometer composite material based on laser sintering (claimed). ADVANTAGE - The method enables to prepare porous graphene enhanced titanium-based nanometer composite material based on laser sintering preventing reaction of titanium with graphene and ensuring good performance of composite nanomaterials. DETAILED DESCRIPTION - Preparing porous graphene enhanced titanium-based nanometer composite material based on laser sintering involves mixing hydrogenated titanium powder, titanium powder and graphene powder together by a certain percentage and placing in a ball mill and adding argon in intermittent in ball mill and mixing to obtain a composite powder. Laser array or line array sintering is performed using laser sintering technology in the composite powders sintered dehydrogenation and hydrogenation of titanium and titanium and graphene sintered body. Titanium hydride powder decomposition of hydrogen in laser sintering rapid fusing process plays the role of preparing microporous. Linear gap is formed between the macroscopic pore sintered material, so preparing a block of porous graphene enhanced titanium-based nanometer composite material.
