Hard Anodising galling
Hard Anodising galling
(OP)
If i hard anodize a small eg, 3/4 inch barrel and also the housing it rotates in, will they be prone to galling? same alloys. Fit is not critical, as long as there free to turn easily. Will be subject to vibration and fuel oil mixture.

Was told it couldnt be done, so

RE: Hard Anodising galling
Its common knowledge that 2 similar metals can gall, and Aluminium can be very bad. I have no idea with Anodised parts tho.
Vibration is the biggest thing, cant balance a single cylinder, and at up to 30,000 rpm, these things vibrate like mad.
Standard steel barrels in Al housings have been known to gall with what seems like plenty of clearance.

Hi.
Your last reply is right. Galling is not an issue between two like-surfaces hard anodized.
