anti-adhesive, low friction coating
Hello,
I want to apply a coating to a steel structure that holds the blades of a scraper because a lot of build-up material is created over it.
The product that we work with is a mixture of pulverized fly ash, bentonite and water (moisture content approx. 15%). The product sticks in the structure of the scraper and when it gets a certain weight falls down contaminating the good product.
I would like to know if you could please suggest a coating that can ensure a really low friction coefficient and certain abrasion resistance.
Besides that, it would be desirable that the process of coating is easy so as to be able to do it without any external help
Many thanks,
Kind Regards

Hi Teresa,
Thin PVD layers of carbon are best suited for such applications. The layers are called DLC (diamond-like carbon) and are applied to polished surfaces in vacuum plasma systems. Sometimes, DLC layers are not deposited directly on polished steel, but with intermediate layers of other hard materials, for example, TiN or CrN. All coatings are produced in vacuum systems.

Vadim

Hello Vadim,
many thanks for the information. However I was thinking about something like a paint that we could apply directly, not that sophisticated and that won'r require external support. Do you have any thoughts?
Thanks,
Kind Regards

Hello,
yes, the issue is that it is not wear resistant.
Thanks anyway

You can try Teflon range, but it is not wear resistant

Hi,
The molybdenum coatings with HVWFS are good but they are expensive.
