Notes:
Molybdenum has many prominent properties, such as high melting point, good thermalproperties, low erosion rate and so on, which make it promising candidate materials for plasma facingmaterials in the next fusion reactor. In the present work, molybdenum coatings were deposited ontothe oxygen-free copper substrates by atmospheric plasma spraying. Different interlayers wereintroduced between the coatings and substrates. SEM, EDS and XRD were used to investigate thephotographs and compositions of these coatings. The bonding strength of the coatings was tested toinvestigate the effect of interlayers on adhesion of the coatings at room temperature and it was foundthat the coating without interlayers showed the highest bonding strength. Water quenching methodwas used to evaluate the adhesion of the coatings under thermal cycling conditions and the resultsshowed that the molybdenum coating with two interlayers possessed of the highest resistance ofthermal cycling wrack
