Nitride Coated
Where do i get boron nitride (or other such materials)?
I am a mechanical engineering student in Kent, England, and for my second year of studying I need to design and build anything i choose over the course of two terms (three hours a week). I would really like to use non-standard materials and opt for something a bit cooler, i.e. make or coat what i want to make in Cubic Boron Nitride. we have basic machinery (CNC machine, lathes etc) but nothing fancy (CVD machines, huge lasers...). What i want to know is if it is possible to buy small quantities of materials such as boron nitride (small amounts being 500g, or 1 kilo) without spending billions. (I'm building a penknife - type thing, since it fits every part of the syllabus, and I want it to be fairly indestructible).
Lovely idea but very difficult to achieve.
You would need to contact trade suppliers and see if they are willing to deal in such a small quantity, or contact local engineering firms who may use the material and would be willing to sell off a small amount, which may not be strictly legal within the articles of formation and trading of the company and which they may therefore have no means of achieving other than a sneaky "didn't get it from me" job which most employees would not take the risk of doing.
What about ceramics? There are ceramic engine blocks these days.
Strong as old socks.
Even ceramic knives on sale in Harrods.
You may have the same problem as with Boron, but searching for a few materials gives you a better chance of actually finding one.
