How to apply a diamond coating?

In my chemistry textbook it says there is a way to apply a ultra-strong diamond coating to any surface. It says all you need to do is get some hydrogen (h2) and methane (CH4) and mix it together, dip the thing you want to coat in the mixture, then use a microwave-like energy source, and the result is a thin diamond coating. Any help, tips, or ideas?|||I've not heard about making diamond coatings using methane and hydrogen.





Applying a diamond coating to all sorts of everyday objects is certainly a good idea. The reason we can't go out and buy diamond-coated hockey sticks or shovels or knives or other items is cost. Not because the raw materials are particularly expensive, the process to do it is tricky. The techniques for applying diamond coatings generally involve very high pressures, or very high temperatures, around 1000 deg C (or both). That's hot enough to make your hockey stick spontaneously combust.





It wouldn't surprise me to see such coatings appear on more everyday objects in the next 15-20 years, as the technology becomes cheaper.
