How to get platinum coating on molybdenum metal

++++++

We wish to obtain a coating of platinum or Pt-Rh alloy on cylinders made of molybdenum metal. The parts will be exposed temperature of 1600 - 1650 degree C and will also come in contact with molten slags, fluxes and glasses. The components are to be used for measurement of high temperature viscosity of melts. Is it possible to have electrolytic deposition of platinum or Pt-Rh alloy, or deposition from some molten salt bath?
