“…Titanium alloys are mainly applied in the sports, ocean and aviation fields owing to the significant properties thereof, including high specific-strength, corrosion resistance, and optimal biocompatibility [1][2][3][4]. In recent years, titanium alloys have been considered to have wide application prospects in the fields of ultra-precision, such as optical and biological fields [5][6][7][8].…”

Titanium alloys have great potential in ultra-precision situations due to the excellent properties, such as high corrosion resistance, high specific-strength and high biocompatibility. However, the application of titanium alloys in ultra-precision field is limited by the poor machinability. There are difficulties in obtaining the optical surface. In this study, the possibility for obtaining optically graded surfaces of titanium alloys by ultra-precision polishing was investigated. Before the ultra-precision polishing, ultra-precision turning with a single point diamond tool was used to get all sample surfaces. But, titanium alloy is difficult to obtain good surface quality by ultra-precision diamond turning. The samples results confirmed that most of the surface roughness values are higher than 30 nm. In order to explore the polishing process, a large number of ultra-precision polishing experiments were conducted. In addition, the effects of different ultra-precision polishing parameters on the surface profiles of titanium alloy Ti6Al4V were investigated in depth. The results show that the average values of surface roughness of titanium alloy parts with ultra-precision turning can be further reduced by 70% or so by ultra-precision polishing. Using a reasonable combination of high spindle speed and large cutting depth, the value of surface roughness can even be lower than 2 nm.

“…Ceramic cutting tools are often applied in the machining of difficult-to-cut materials like hardened steels [1], nickel alloys [2], Inconel [3], or titanium alloys [4]. Ceramics based on alumina are important materials for this application because of their properties such as hardness retention, compressive strength, and chemical inertness at elevated temperatures, which are better than those of tungsten-cemented carbides [5].…”

Effect of SiC Addition to Al2O3 Ceramics Used in Cutting Tools

In this study, the effect of the addition of silicon carbide to alumina ceramics commonly used in cutting tool applications is addressed. Performance of Al2O3–SiC composite cutting inserts during the machining of hardened steels and ductile iron was compared to the results obtained for a cutting tool made out of 99 wt.% Al2O3, Al2O3–TiC, Al2O3–TiC–ZrO2, and Al2O3–TiN. In almost all tests, the composite with silicon carbide demonstrated better wear resistance, longer tool lifetime, and the ability to cut at higher speeds. The enhanced properties of cutting tools with SiC can be attributed to the morphology and dimensions of the inclusions in the matrix as well as to the strength of the interphase boundaries, small porosity, and lack of high inner stresses in the volume.
