Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy ( martensite - austenite , austenite - ferrite ), known to be associated with strongly enhanced mechanical properties.
The process starts with a standard salt bath nitrocarburizing cycle, which produces a layer of ε iron nitride. [4] Next, the workpiece is mechanically polished; typical polishing processes include vibratory finishing, lapping, and centerless grinding. Finally, the workpiece is re-immersed into the salt quench bath for 20 to 30 minutes, rinsed ...
The final matte, non-glare finish meets or exceeds stainless steel specifications, is 85% more corrosion resistant than a hard chrome finish, and is 99.9% salt-water corrosion resistant. [34] After the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the finish were to wear off.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish. The typical precision of a surface grinder depends on the type and usage, however ±0.002 mm (±0.0001 in) should be achievable on most surface grinders.

Platinum nitride and osmium nitride may contain N 2 units, and as such should not be called nitrides. [11] [12] Nitrides of heavier members from group 11 and 12 are less stable than copper nitride (Cu 3 N) and zinc nitride (Zn 3 N 2): dry silver nitride (Ag 3 N) is a contact explosive which may detonate from the slightest touch, even a falling ...
In today's puzzle, there are six theme words to find (including the spangram). Hint: The first one can be found in the top-half of the board. Here are the first two letters for each word: FL. AS ...
