Why on STEAM biomass gasification, at some critical point in the steam/biomass ratio, starts to reduce and negatively affect the H2 concentration ?

I would be interested to know if you have any thoughts on how this limitation could be addressed, since usually the S/B ratio affects the Hydrogen concentration positively.

Hello Badr,

Please refer to this article.

Wear performance of (nc-AlTiN)/(a-Si3N4) coating and (nc-AlCrN)/(a-Si3N4) coating in high-speed machining of titanium alloys under dry and minimum quantity lubrication (MQL) conditions, by Zhiqiang Liu et. al, 2013.

Hope this helps.

Best of luck!

Badr Zouhair

thank you so much Mr Youssef

J. M. Sanchez

Monolithic AlTiN (66/33 at ratio between Al and Ti) gives excellent performace in milling operations. Ti-6Al-4V

thank you so much Mr J. M. Sanchez for your interissed answer , but can you suggest me a paper , because i need to justify that choice!

Modern PVD TiAlN or AlTiN coated cutting tools are expected to provide good performance in machining of Ti-alloys.

The following story is that of a failure of TiB2 coated tools in machining Ti-alloy even under cryogenic cooling.
