Abstract
1308819 Nitrlding ELEKTROPHYSIKALISCHE ANSTALT BERNHARD BERGHAUS 17 Nov 1970 [12 Dec 1969] 54624/70 Headings C7U The trochoid housing of a rotary piston machine is nitrided over part of its surface by means of a glow discharge in an atmosphere containing nitrogen, the remainder of the surface being coated to inhibit the glow discharge, for at least 5 hours, at a pressure of 0À1 - 5 mmMg and using an operating voltage of at least 500V., the thickness of the iron nitride being kept below 10Á-
