This is a great way to add a double layer to steel in a Tungsten coating, like a cam shatt on your car, or the bearings. i.e. steel on the inside and a near indestructible friction free coating on the outside.
Applications of this are endless and is the stuff of the space age.
There is no massive Tones, Kg's needed yet as it uses a very small amounts. .

My Engineering teacher in my College days, told us that he worked on the Ford development team in Australia. He said there was a meeting with the managment prlcks, and they said, "how can we make the heater in the car break down after 13 months".
He told us he stood up and walked out of the meeting while telling them, "I dont design things to break".
Lower pay as a teacher, but self respect intact.
