      Sánchez, Samuel; Colmenares, Franklyn; González Lizardo, Ángel E.; Leal Quirós, Edbertho (Polytechnic University of Puerto Rico, 2008)
      This work presents an ongoing effort to develop an automatic measurement system for plasma diagnostics at the Plasma Engineering Laboratory of Polytechnic University of Puerto Rico, along with an example of its operation. ...

    • Experimental Design of a High Vacuum System for PUPR-MC Plasma Machine 

      Rivera Varona, Ramón; Colmenares, Franklyn; Leal, David; Lleonart, Giovanni (Polytechnic University of Puerto Rico, 2008)
      In vacuum technology it is customary to divide a large pressure region (as of today, covering 16 orders of magnitude) into single, smaller regions. These divisions are somewhat arbitrary. Thus, the chemists frequently refer ...

    • High Density Plasma Nitriding on Stainless Steel Alloys at PUPR-MC Plasma Machine 

      Rivera, Ramón; Colmenares, Franklyn; Lleonart Dávila, Giovanni; Leal, David; Gaudier, Jorge; González Lizardo, Ángel E.; Leal Quirós, Edbertho; Burgos Saldaña, Gilmer (Polytechnic University of Puerto Rico, 2008)
      A novel method of nitriding at high current levels at Polytechnic University of Puerto Rico Mirror Cusp plasma machine (PUPR-MC) has been performed. Nitrogen ions implantation or plasma nitriding increases the hardness at ...
