Al and Si? flux?

  1. Jan 25, 2008 #1
    Al and Si?? flux??

    to creat a film of alloy Al and Ti we use to flux of each element and a substrat.
    if the flux of Al is double of that of Ti, then we obtain an alloy on the substrat AlTi or what???

    What is the substrate?

    I believe the goal is something like TiAl (titanium aluminide), although Ti3Al is apparently of interest as well.

    its not about the type of substrat. its about a pulverisation of two source Al and Ti do depose an alloy on the substrat. if the flux of Al pulverized equal = 2* flux of Ti, so which alloy we obtain??

    Is that on an atomic basis? or mass, which would be different.

    With Al = 2*Ti, I would imagine a mix of Ti-Al, and Ti-Al3, not knowing anything other information.

    Is this a plasma spray, vapor deposition, or sputtered coating?

    its sputtering

    Again, you can't calculate it. If it is done usings sputtering (what kind?) you have a few process parameters to play around with; mainly temperature.
    For practical film depostion it will also -to some extent- be specific to the equipment you are using.
    The only way to do this properly is to deposit a lot of films under different conditions and analyze them (using XRD and some type of surface spectroscopy, e.g. Auger): this will give you a "map".
