Branding is paramount in any industry where choice is in abundance. Therefore, it is important to maintain the reputation of your brand so that the cars our customers manufacture today will still look good and perform well in 10 years’ time.
Saint-Gobain engineers understand the importance of branding and reputation for our customers and so have developed impressive corrosion resistant solutions for parts that last.
To ensure our customers have confidence in the rigorous testing performed by our engineers, we test to international standards, specifically ISO 9227:2017 “Corrosion tests in artificial atmospheres -- Salt spray tests”.
A controlled corrosive environment allows more accurate indications of corrosion resistance performance in the field than if no test were performed. This way our customers will not be met with any nasty surprises during the operating lifetime of the part or system. In addition to a salt spray test, we can also perform other common tests such as cycle condensate tests or customer specific testing if required.
The steel backing layers, that can be found on a selection of our NORGLIDE® solutions, are mechanically or galvanically zinc plated resulting in corrrosion resistant bearings. Utilising zinc plating in this way ensures that NORGLIDE® Bearings meet customer specifications for salt spray exposure without any red rust.
For even tougher bearings that remain corrosion resistant in the harshest of conditions, Saint-Gobain can provide NORLGIDE® SMALC and NORGLIDE® TALC solutions that comprise an aluminium-clad steel backing layer as seen in figures 2 & 3. The corrosion resistance of the aluminium-clad NORGLIDE® solutions means an impressive 1,000 + hours of salt-spray exposure with no red rust.
This material works well for automotive applications as the majority of automotive hinge parts are Zn or ZnNi coated steel housings. The Aluminum cladded surface for NORGLIDE® TALC & SMALC is a good choice to work with Zn or ZnNi because the high affinity between Zinc and Aluminum means reduced galvanic corrosion.
