Introduction Development of materials suitable for VIS-transparent immersion media with a high refractive index is an actual applied and a complicated scientific and technical problem.
Such materials are mainly required for geological investigation of minerals (hereinafter referred to as objects) and the evaluation of inner defects of natural diamonds and other VIS-transparent high-refractive objects.
To date, the number of VIS-transparent materials with a refraction index close to 2.41 has been considerably limited.

The reclamation of construction waste means to recover the useful materials and resources.
The environmental impact of construction wastes is permanent and accumulated, and the components are increasing diversified and the proportions of non－degradable materials, compounds, and organic materials are increasingly larger, so, the secondary contaminations are also increasing severe.

So, titanium alloys are widely used in aviation in abundance and are hailed as a kind of strategic metal materials making human to the space age.
However, titanium alloys belong to typical difficult-to-machine materials because of small deformation coefficient, small coefficient of heat conductivity and good chemical affinity to cutting tool materials in the case of both high cutting temperature and great cutting force on the unit contact area.
Materials of the tools usually are YG cemented carbides and high speed steels with high performance.
With the progress of materials technology, super-hard cutting tool material and coating cemented carbide have been widely used [2].
According to the table 2, selected tool materials meet the requirement of strength.

Intorduction Ion implantation, as a method of targeted influence on the structure and properties of materials, is still insufficiently studied in a number of aspects.
