Biomedical Engineering Aims and scope

Conclusions

1. Measurements have been made on the effects of HF nitrogen and argon-nitrogen plasmas produced at low pressures on titanium alloys. The largest effect comes from treatment with a nitrogen-argon plasma.

2. Allowance must be made for the specimen size including treatment conditions. The treatment conditions are independent of the size for specimens heated to the same temperature.

3. There are optimum treatment conditions that simultaneously increase the microhardness and reduce the roughness.

4. The largest effects on the surface parameters of the titanium alloys are produced by the heat flux in the processes occurring on ion-electron recombination.

5. The optimum treatment conditions do not affect the residual stresses in the alloy but increase the fatigue limit and the working life.

6. The optimum HF plasma treatment conditions have been devised for microsurgical and ultrasonic surgical instruments.
