Glock 17 pistol with a black Parkerized topcoat. Glock Ges.m.b.H., an Austrian firearms manufacturer, uses a black Parkerizing process as a topcoat to a Tenifer process to protect the slides of the pistols they manufacture. After applying the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the Parkerized ...
Glock Ges.m.b.H., an Austrian firearms manufacturer, utilized the Tenifer process until 2010, to protect the barrels and slides of the pistols they manufacture. The finish on a Glock pistol is the third and final hardening process. It is 0.05 mm (0.0020 in) thick and produces a 64 Rockwell C hardness rating via a 500 °C (932 °F) nitride bath ...
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 ...
Rust bluing is also used on shotgun barrels that are soldered to the rib between the barrels, as hot bluing solutions melt the solder during the bluing process. Large scale industrial hot bluing is often performed using a bluing furnace. This is an alternative method for creating the black oxide coating.
The time the part spends in this environment dictates the depth of the case. The hardness is achieved by the formation of nitrides. Nitride forming elements must be present for this method to work; these elements include chromium, molybdenum, and aluminum. The advantage of this process is that it causes little distortion, so the part can be ...
The black currant-y aroma and taste of this French red blend is perfectly appealing, as are the firm (but not aggressive) tannins and brisk (but not searing) acidity. Missing Thorn Red ($30) Food ...
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.
Listen up: Our senior tech writer, Rick Broida, has spent the past two decades testing (and testing, and re-testing) hundreds of earbuds. So, when he's surprised by just how good a $40 pair ...
