Laser-Aided Directed Energy Deposition of Steel Powder over Flat Surfaces and Edges
In the framework of Additive Manufacturing of metals, Directed Energy Deposition of steel powder over flat surfaces and edges has been investigated in this paper. The aims are the repair and overhaul of actual, worn-out, high price sensitive metal components. A full-factorial experimental plan has been arranged, the results have been discussed in terms of geometry, microhardness and thermal aff...
متن کاملEnergy deposition depth of a Nd:YAP laser in human skin
Nd:YAP laser emitting at 1342 nm appears promissing for nonablative skin rejuvenation, due to lower absorption in epidermal melanin and higher absorption in water as compared to the 1064 nm light from Nd:YAG lasers. The aim of our study was to verify these relations in vivo and quantify the energy deposition depth of a Nd:YAP laser in intact human skin. A comparison with the results obtained wi...
متن کاملBoron films produced by high energy Pulsed Laser Deposition
Micron-thick boron films have been deposited by Pulsed Laser Deposition in vacuum on several substrates at room temperature. The use of high energy pulses (>700 mJ) results in the deposition of smooth coatings with low oxygen uptake even at base pressures of 10 -4 -10 -3 Pa. A detailed structural analysis, by X-Ray Diffraction and Raman, allowed to assess the amorphous nature of the deposited f...
متن کاملPartitioning of energy during lactation of primiparous beef cows.
For a beef cow to continue in an annual production cycle, she must rebreed within 3 mo after calving. Malnutrition during this period frequently results in failure of the cow to become pregnant. The energetic needs of the cow are increased by lactation, and additional energy is required for growth of the primiparous cow. Determining energy expenditures during the first 40 to 60 d postpartum is ...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
