PROCESS FOR THE MANUFACTURE OF BLACKENED SURGICAL NEEDLES
In a process for the manufacture of blackened surgical needles, unfinished needles produced from a chromium-containing steel are dipped into an acidic aqueous solution with a chromium (VI) compound. The solution has a temperature in the range from 10 DEG C to 40 DEG C, preferably in the range from 1...
