The biological activity, biocompatibility, and corrosion resistance of implants depend primarily on titanium dioxide (TiO2) film on biomedical titanium alloy (Ti6Al4V). This research is aimed at getting an ideal temperature range for forming a dense titanium dioxide (TiO2) film during titanium alloy cutting. This article is based on Gibbs free energy, entropy changes, and oxygen partial pressure equations to perform thermodynamic calculations on the oxidation reaction of titanium alloys, studies the oxidation reaction history of titanium alloys, and analyzes the formation conditions of titanium dioxide. The heat oxidation experiment was carried out. The chemical composition was analyzed with an energy dispersive spectrometer (EDS). The results revealed that titanium dioxide (TiO2) is the main reaction product on the surface below 900°C. Excellent porous oxidation films can be obtained between 670°C and 750°C, which is helpful to improve the bioactivity and osseointegration of implants.

  • Answer: The powder loss of putty powder is mainly related to the quality of hydrated lime (calcium hydroxide) and has little to do with HPMC. A low calcium content in hydrated lime and an inappropriate ratio of CaO to Ca(OH)2 can both cause powder loss. If there is some relation to HPMC, it would be that poor water retention of HPMC can also cause powder loss. For specific reasons, please refer to question 9.

  • At its core, HPMC consists of a linear chain of glucose units, which are the building blocks of cellulose. These glucose units are connected by beta-1,4-glycosidic bonds, forming a long, unbranched polymer. However, what sets HPMC apart from native cellulose is the introduction of hydroxypropyl and methyl groups through a process called etherification.
  • When buying hydroxyethyl cellulose, it is important to consider the quality of the producthydroxyethyl cellulose where to buy.
