Projects

Vacuum thermal processing of stainless steel rods

Reimbursement for processing 10 samples. The funder will provide all materials and process parameters. This is not a R&D project and there will no liability to the OU regardless of process outcome. The generated income will be used to cover my other research costs.

HEIF consumables budget - reimbursement from collaborator

Reimbursement for consumables paid for from HEIF used in collaboration that led to sale of technology by AF Pipes.
