The PPK and PP are still manufactured by Walther, but the PP went out of production between 1999 and 2024 [14] and have been widely copied. The design inspired other pistols, among them the Soviet Makarov , the Hungarian FEG PA-63 , the Czechoslovakian Vz. 50 , the American Accu-Tek AT-380 II, and the Argentine Bersa Thunder 380 .
The slide and other metal parts of the pistol are Tenifer treated (a ferritic nitrocarburizing process also used on Glock pistols). The Tenifer finish is between 0.04 mm (0.002 in) and 0.05 mm (0.002 in) in thickness, and is characterized by extreme resistance to wear and corrosion; it penetrates the metal, and treated parts have similar ...
According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘metal on which a coating material (e.g. paint, film…) has been applied by coil coating’.When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties.
Manurhin, officially known as Manufacture de Machines du Haut-Rhin, in Haut-Rhin, France started by manufacturing Walther PP, PPK, and PPK/S model pistols in 1952. The guns were imported into the US from 1953 by Tholson Co. and from 1956 by Interarms. In 1984, Manurhin imported their new models directly; they were marked Manurhin on the left ...
Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting. [1] [2] [3] It is one of the most common types of conversion coating.

A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion , to improve the adherence of other coatings, for lubrication , or for aesthetic ...
