A method of producing a free standing PCD comprises forming a mass of combined diamond particles and precursor compound(s) for the metals of the metallic network by suspending the diamond particles in a liquid, and crystallising and /or precip -itating the precursor compounds in the liquid. The mass is then removed from suspension by sedimentation and/or evaporation to form a dry powder of combined diamond particles and precursor compound(s). The powder is subjected to a heat treatment to disso -ciate and reduce the precursor compound(s) to form metal particles smaller in size than the diamond particles to provide a homogen -eous mass. This is then consolidated using isostatic compaction to form a homogeneous cohesive green body of a pre-selected size and 3-dimensional shape. The green body is subjected to high pressure and high temperature conditions such that the metallic mater -ial wholly or in part becomes molten and facilitates diamond particle to particle bonding via partial diamond re-crystallisation to form a free standing PCD body.

In a titanium material, when a chemical composition of a surface is analyzed by X-ray photoelectron spectroscopy, the titanium material contains, as a composition of the surface, Zn: 0.1 atom% or more and Ca: 0.5 atom% or more, and the titanium material contains, as a composition of a surface oxide film, C: 20.0 atom% or less and F: 5.0 atom% or less.

A method for preparing an aluminum carbon composite by using a foam aluminum includes the following steps. Electromagnetic stirring and drying are performed on the foam aluminum and a carbon material to obtain a foam aluminum preform; an aluminum block is melted into aluminum liquid, the aluminum liquid is adjusted to qualified aluminum liquid, the qualified aluminum liquid is cooled to a temperature of 620˜650° C. and keeping the temperature to make the qualified liquid aluminum become a semi-solid state, then the foam aluminum preform is pressed into the qualified liquid aluminum and performing electromagnetic stirring. A mold is heated to a certain temperature and extrusion molding is performed to obtain a carbon reinforced aluminum matrix composite material. The method overcomes a problem that the carbon material and the aluminum matrix have poor wettability and are not easy to be added into the aluminum matrix.
