high temperature curing of dry film lubricant on Aluminum tube?

high temperature curing of dry film lubricant on Aluminum tube?

high temperature curing of dry film lubricant on Aluminum tube?

(OP)
Does anyone know applying high temperature curing(150 C for 10 minutes) for a dry film lubricant on aluminum 6061 T6 (tube,sheet) cause any critical change in the microstructure that may affect the mechanical properties of the part?

Thanks in advance
Best regards

RE: high temperature curing of dry film lubricant on Aluminum tube?

There should be no problem, as the minimum aging temperature for 6061 T6 is 320 +/- 10 F (160 +/- 5 C).

Hello TVP ,thank you for your comments

Yeah you are right , it is approximately the temperature for obtaining T6 from T4 , but i dont know what is the effect after obtaining T6 since it is kind of comlicated kinetics if there is some kind of coarsening of precipitates and lowering the strength a little bit?

let me add some other combinations to my question
for 60 min for 150 C
or 30 min for 180 C?

What would be the effects of these?

RE: high temperature curing of dry film lubricant on Aluminum tube?

The proposed exposures to 150 °C won't affect your part if you aged them at or above 150 °C.

Any exposure to 180 °C will reduce the strength.

Cory

Hi.

Cory's right.  Resistance to stress fracture, expansion of the micro structure, for 6061-T6, is unchanged when temperatures are held below 375 F.

If the properties you seek are superficial, have you considered wear resistant coatings?

For more information, see:

Good luck!
