I’m supposed to write an essay on innovative ways to surface-harden steel. I came across boronizing with Borocoat, which is a technology developed by Bortec, a German company. Borocoat layers are supposed to improve hardness, adhesion and resistance against abrasive wear. I’m honestly intrigued but the website only tells me so much. It’s certainly not enough to write a 10-page essay. Can anyone link me to more borocoat documents?
