Corrosion behavior of Ti6Al4V molvbdenized by double glow plasma alloying
To meet the requirement of developing new surface treatment of titanium alloys,a molybdenizing was conducted on Ti6A14V using double glow plasma surface alloying.This paper mainly investigated the influence of molybdenizing on the corrosion behaviors.The microstructure and phase constituent of the molybdenizing layer were examined by means of SEM and XRD respectively.Comparisons of the electrochemical behaviors between the molybdenized specimens and untreated titanium alloy were carried out in 3.5% NaCl solution and 5% HCl solution,respectively.The results show that the molybdenizing layer is homogeneous,continuous,and dense which is composed of deposited layeT and diffused layer.Distribution of Mo changes with the depth of the diffusing layer increasing.The results of the electrochemical experiments indicate that corrosion potentials of the alloying layer have been lifted under the same corrosion condition.Comparing with the bare matrix,the alloying had not reduced the corrosion resistance.
