A tank with sufficient armour could resist the largest anti-tank guns then in use. RHA was commonly used during this period (combined with other plate alloys and cast steel armour), and the power of anti-tank guns was measured by the thickness of RHA they could penetrate. This standard test has remained in use despite the modern usage of many ...
The advanced Kontakt-5 explosive reactive armour on this T-90S is arranged in pairs of plates, giving the turret its prominent triangular profile.. An element of explosive reactive armour (ERA) is made of either a sheet or slab of high explosive sandwiched between two metal plates, or multiple "banana shaped" rods filled with high explosive which are referred to as shaped charges.
US Marine Corps M1A1 on a live fire exercise in Iraq, 2003. It is a modern Main Battle Tank that extensively uses Chobham armour. In the United Kingdom application of Chobham armour was delayed by the failure of several advanced tank projects: first that of a joint German-British main battle tank; then the purely British MBT-80 programme.
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
Petroleum-based rust-inhibitors provide several benefits, including the ability to creep over metal, covering missed areas. [citation needed] Additionally, a petroleum, solvent-free rust inhibitor remains on the metal surface, sealing it from rust-accelerating water and oxygen. Other benefits of petroleum-based rust protection include the self ...
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
It is a difficult product to apply evenly, offers minimal protection and is generally best used for small fast repair jobs and touch-ups. [ 2 ] [ 3 ] The "hot" process is an alkali salt solution using potassium nitrite or sodium nitrate and sodium hydroxide, referred to as "traditional caustic black", that is typically done at an elevated ...
RKG-3 is a series of Soviet anti-tank hand grenades. It superseded the RPG-43 , RPG-40 and RPG-6 series, entering service in 1950. It was widely used in the 1973 Arab–Israeli War and remained a common weapon into the 2000s and early 2010s, being favoured by Iraqi insurgents during the American-led occupation .
