Corrosion Protection Just Went From Better to Best

Corrosion Protection Just Went From Better to Best

大气腐蚀 is the deterioration and destruction of a material and its vital properties. Examples include discoloration, rust, pitting, and cracking. 对于一些制造商来说, factoring in the possibility of corrosion, especially when metal-based material is involved, 是很重要的. In the natural gas distribution industry in particular, this is a major concern as the steel or iron parts are vulnerable to a low-level electrical current that can accelerate corrosion. 从那里, rust and degradation can wear down the part sooner, leaving it vulnerable to potential leaks, 安全问题, 而且失去了外观吸引力. Thankfully, coatings and paints are an effective solution for reducing corrosion effects.

A.Y. McDonald is excited to share an exclusive coating that raises the bar of corrosion protection to a whole new level by introducing ArmorGalv®. 它改变了游戏规则! This thermal-diffused zinc coating, 还有面漆封口剂, creates a bond with the casting that provides corrosion resistance for parts made of steel and iron. The process of applying thermal-diffused coatings is standardized in accordance to ASTM A 1059 Standard Specification for Zinc Alloy Thermo-Diffusion Coatings (TDC) on steel fasteners, 硬件, 以及其他澳门葡京赌场赢钱技巧. ArmorGalv® also comes with the following benefits:

• 环境友好型
• Uniformly applied on all external and internal surfaces to create a bond with the casting
• Commonly used in marine and automotive environments, as well as electrical utility applications
• Provides excellent adhesion properties for paint
• Paint can be applied over ArmorGalv® for additional corrosion benefits

Based on the American Society of Testing and Materials (ASTM) standards, multiple tests can be used to measure corrosion. However, the Salt Spray Test per ASTM B117 is the most common. To effectively conduct this test, materials must be placed in a salt fog chamber. 从那里, a 5% NaCl solution is atomized at 95°F with a neutral pH or 6.5-7.2. The parts are kept continuously in the fog without touching any other metallic or corrosive material. Materials are checked periodically for rust or decay with the test duration determined by the manufacturer.

A.Y. McDonald performed salt spray testing with the ArmorGalv® coating applied to cast iron rough castings. In accordance with ASTM A 1059, the thickness of the coating applied was designated at Class 25 (0.98密耳厚). The sample below was tested to 3000 hours of salt spray exposure in accordance to the ASTM B117 Standard Practice for Operating Salt Spray (Fog) Apparatus.

**Test stopped at 3000 hours without failure
*Uncoated black iron will rust in 24 hours of less after initial exposure to salt spray environment

由于结果, by creating sacrificial layers of iron and zinc alloys, parts can last in an A2LA accredited salt spray environment well over 3000 hours before red rust appears on the base material compared to 350 hours for other coatings.

在严重的情况下, when corrosion meets a natural gas distribution part, the lifespan of the product can go downhill. 知道了这一点, ample amounts of research and resources are put toward rectifying the industry-wide issue. A.Y. McDonald does our part by applying coatings to our products that reduce the effects of corrosion, 尤其是ArmorGalv®. 除了, we continue to take corrosion prevention seriously by performing tests such as the Salt Spray Test.
