[Upgrading the corrosion resistance of medical instruments made of chromium steel of the martensite class with electrochemical polishing]. / Povyshenie korrozionnoi stoikosti meditsinskikh instrumentov iz khromistykh stalei martensitnogo klassa pri élektrokhimicheskom polirovanii.

An electrolyte with surfactant admixtures has been specially designed for finish electrochemical polishing of medical instruments. It enables reducing in requirements for surface roughness and the size of labor-consuming operations when grinding and polishing.

[Use of titanium alloys for medical instruments]. / O primenenii titanovykh splavov dlia meditsinskikh instrumentov

On the ground of an analysis into properties of titanium and its alloys the fields of their possible utilization for making various medical instruments are proposed. Because of their insufficient hardness and wear-resistance the titanium alloys cannot be recommended for making medical instruments with thin cutting edges. For the reasons of their insufficient strength, low wear-resistance and substandard modulus of elasticity, it is inexpedient to use titanium alloys in making many types of clamping medical instruments. Nor is it advisable to employ titanium alloys in handles of the instruments, for this may lead to a contact corrosion of their working parts. The use of titanium alloys is recommended for making bone-joining members, retracting medical instruments, of the spatula and speculum types, some kinds of non-magnetic pincers and ultrasonic medical instruments.
