Nano-coating

A couple of years ago i was working with an independent testing facility that was a leader in coating evaluation; applications and performance. So we were dealing with both sides of the fence, but most of our research and clients were specifically interested in wear protection and friction reduction.

Depending on how "nano" you are looking, I think that they could help you out...depending on your actual requirements.

Thanks for your response.

Actually I am not hung up on NANO. Even a micro-coating will be acceptable--provided it meets my requirements.

call me and i will tell you of a couple

While not nano technology, thermal spraying of a suitable coating such as inconel will fix this issue.

Thermal spray coating is one option. Please write to info@technovations.ws for more help.

kamanju,

While I have no first hand experience with the company, and do not know how "successful" their product line is, there is a company that has developed nano-coatings.

Check out their web site:

Just my $0.02

I looked at that link and fail to see anything that convinces me that their product is anything other than chemistry. "Nano" is so overused and misused today. I work for a nanotechnology company and we actually produce numerous optical products with tolerances of ~5 nm. It takes a SEM to actually see the products. If they were incorporating nanotubes or something similar in their products okay, but they don't say that. Not convinced.

These coatings will not help since they are insulators ( bad conductor of heat) . My requirement is that the thermal conductivity should not come down as comapared to that of the parent metal

I am afraid these will not help since they are all insulators . My requirement is that the coating should not bring down the thermal conductivity .

Yes, but not through technology transfer. The issue lies in the definition of "NANO". I have worked in the coatings industry for many years and have developed quite an array of coatings and coating solutions. The key is NANO crystalline. Most of the Roderick out there about NANO is focused strictly on its size. Anything that falls under one micron is being deemed as NANO size.

Years ago, we would call this sub-micron. The true calling of NANO technology is the unique properties the material has which differ from the same material of a larger size (substitute electron roll plying here). Take tungsten carbide for example, which is widely used in coatings and cutting tools. The premise here is the smaller the starting carbide powder (particles) the better the wear resistance. This statement is true in all accounts. Growing single crystal (grains) of carbide and making tooling from them is a great idea until you heat (sinter) the tooling. The heat grows the Crystal making the grain no longer NANO crystalline but rather just plain old NANO size.

So smaller the better right, not so. The NANO crystalline grain contains properties such as a unique shape and certain flexibility that the non Crystal grain doesn't have. In the end you just wind up with allot of really sub-micron stuff that cost more and makes for great press.

By the purest definition of Thermal Spray one could surmise the use of HEAT.

We have developed all kind of coatings. Below there's a link to some of our applications, but over the last 20 years we have also developed nanocrystalline coatings, multilayer coatings (some of the layers in the nanometric range) and nanocomposite coatings.

We have several technologies ready to transfer.

Thanks for responding.

Went through your website.

Am writing to you separately.

Tesla NanoCoatings Limited has developed innovative nanocoating systems designed to inhibit corrosion of steel by forming the both toughest barrier film and a cathodically protective coating. The Tesla coating systems utilize galvanically inactive single wall carbon nanotubes (SWNT) in conjunction with sacrificial metals to produce both the toughest available barrier coating and galvanic reactivity with the substrate. The SWNT facilitates the transfer of electrons by creating an electron path through the binder and between the cathodic substrate and anodic sacrificial metals. The main function to shift the potential of the environment to a less corrosive cathodic potential in the inevitable event of a coating defect.

The coatings are available commercially at:

Can this type of coating withstand up to maximum 200 deg c environment may be sulphure in this atmosphere. It should be with anti scratch property and tell me about this coating lifespan for payback period calculation.

I want to use this coating inside esp hopper to reduce or avoid material clogging and accumulation inside.
