: I would appreciate if I could have any information on correct (optimal) structure of lanthanum hexalumina sprayied by APS.
: i'm looking for information espesially on the phisic field (porosity, roughness etc.)
: will be greate to get some photos
Hi Marcin
This coating is new to me. I assume the coating is primarily for thermal barrier applications.
You may find this link of interest (the only info close to the subject I could find)
Thermal Barrier coating with lanthanum magnesium hexaaluminate (LMH)
http://www.uni-stuttgart.de/ifkb/pdf/15-e.pdf
If you come across any additional information I also would be interested, particularly if this coating shows promise of improvements over the yttria partially stabilized zirconia coatings.
Regards Gordon
