Nitrocementation of gears
- 14 Downloads
In manufacturing high-quality gears precisely one-third of the whole tolerance must be allowed for machining and two-thirds for nitrocementation.
The dependability and durability of drilling apparatus using nitrocementated gears of steel 30KhGT are far greater than those with nitrided gears of steel 30KhYuA.
Nitrocementation is a shorter process than nitriding and nitrocementated gears have higher mechanical properties and less warping than those of nitrided gears.
