Friction coefficient of alumina ceramic?
Friction coefficient of alumina ceramic?
(OP)
I would like to know what the coefficient of friction is for 90 - 92% alumina ceramic tile. I know that there are many variables that affect it but I do not need precise numbers. I just want to know how alumina ceramic compares to mild steel, stainless steel, and/or chrome carbide overlay. I am looking for a wear-resistant material for coal chutes but we also need to minimize friction and thus material hang-up and plugging.





RE: Friction coefficient of alumina ceramic?
200°C. The manufacturer of the tiles should be able to give you some information.
You have to be very careful where you use Al around any coal handling equipment.
