    I am sorry to disagree with Mr. Rowe but I feel that it is very
    unlikely there is any "microalloying" going on between titanium and
    gold...This would only happen at expremely elevated temeratures and
    the process would take time...It would be happening through the
    process of dissolution which requires time and residence "or
    contact:" as liquids....I don't see it as possible. I am very
    doubtful about it...( I have been in the ti industry 15 years and
    can tell you from experience in the manufacture of titanium
    alloys)... 

    You could be getting dust contamination if your surroundings are not
    kept clean but the dust will be highly oxidized ( and pacified) and
    unrecognizable as titanium as an element. 

    It does have different coefficient of xpansion tendencies from gold
    so you could be getting stresses as opposed to contamination. 

    I am interested in what you are seeing...Tell me more
