: Iam involved in the rotating equipment on the plant with regards to maintenance, we sometimes need to get the bearing journals on the shafts sprayed what method would you suggest and why.
: It has been suggested that we use chrome oxide coating on bearing journals and metal spraying on areas where oil seals and o rings are present.
Hi David
All the thermal spray processes (flame, plasma, arc and HVOF) with a large selection of coating materials are successfully used on bearing journals. The choice depends on the bearing type, operating conditions and economics. Plasma sprayed chromium oxide is good for use on surfaces running against mechanical seals.
