Argon ion implantation inducing modifications in the properties of benzene plasma polymers
(Elsevier B.V., 2002-05-01)
Benzene plasma polymer films were bombarded with Ar ions by plasma immersion ion implantation. The treatments were performed using argon pressure of 3 Pa and 70 W of applied power. The substrate holder was polarized with ...
Low temperature plasma nitriding and nitrocarburising of a superaustenitic stainless steel
(2016-01-01)
Low temperature surface engineering of stainless steels by dissolving large quantities of nitrogen and carbon has become a favorable technological process. Such treatments usually yield the so-called expanded austenite, ...
Modification of plasma polymer films by ion implantation
(ABM, ABC, ABPol, 2004-09)
In this work, thin polymer films were prepared from acetylene and argon radiofrequency (13.56 MHz, 80 W) glow discharges. Post-deposition treatment was performed by plasma immersion ion implantation in nitrogen or helium ...
Uso do soro autólogo condicionado e do plasma rico em plaquetas na terapia ortopédica de equinos
(Univ Estadual Londrina, 2014-01-01)
Musculoskeletal injuries that occur in horses during sports activities are often disabling and require a long period of treatment and rehabilitation, most resulting in scar tissue, predisposing to recurrence. In search of ...
Surface Corrosion of Ti-16Si-4B Powder Alloy Implanted With Nitrogen by Plasma-Based Technique
(Institute of Electrical and Electronics Engineers (IEEE), 2011-11-01)
Titanium materials with a new ternary phase, Ti(6)Si(2)B, can be manufactured by high-energy ball milling and further sintering of titanium, silicon, and boron powders. In this paper, hot pressing was chosen to compact the ...
Uniform surface modification of polyethylene terephthalate (PET) by atmospheric pressure plasma jet with a horn-like nozzle
(2018-10-25)
This work reports on surface modification of polyethylene terephthalate (PET) polymer by an atmospheric pressure plasma jet (APPJ) operated with argon. A distinguishable feature of this device is that it terminates with a ...
Increasing fatigue resistance of AISI 4340 steel by nitrogen plasma ion-implantation
(Elsevier B.V., 2019-01-01)
Failures in structural components due to cyclic loading are associated with materials surface damage. Coatings deposited by different surface processes are more or less effective to improve the degradation resistance of ...
Surface Modification of Polycarbonate by Atmospheric-Pressure Plasma Jets
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11-01)
Plasmas have been frequently employed to modify material surface properties; however, many of these processes are not suitable for treating sensitive materials and biological objects that cannot withstand vacuum and/or ...
Cold Atmospheric Pressure Plasma Jet Reduces Trichophyton rubrum Adherence and Infection Capacity
(2019-01-01)
This study aimed to evaluate the effects of cold atmospheric pressure plasma (CAPP) jet on Trichophyton rubrum growth, germination and adherence to nail. The effects of plasma jet on T. rubrum conidia germination and on ...
Antimicrobial and protective effects of non-thermal plasma treatments on the performance of a resinous liner
(2020-09-01)
Objective: Overcoming substantial shortcomings of soft liners as physico-chemical changes and liner-biofilm-related infections remains a challenge in the rehabilitation treatment. In this study, protective non-thermal ...
