COLD SPRAYED COATINGS WITH DUAL NANOPARTICLE REINFORCEMENTS FOR WEAR AND CORROSION PROTECTION
(Monterey, CA; Naval Postgraduate School, 2020-06)
As a form of additive manufacturing, the use of cold spray has made significant strides since different-sized particles were explored in the process. There is proof that micron-sized particles down to nanoparticles enhance ...
MECHANICAL PROPERTIES OF NANO BORON NITRIDE AND MICRO BORON CARBIDE REINFORCED ALUMINUM COLD SPRAY COATINGS
(Monterey, CA; Naval Postgraduate School, 2022-12)
With regards to cold spraying, wear resistant metal coatings reinforced with boron nitride nanotubes (BNNTs) have remained unexplored when compared to carbon nanotube-based composites. Using commercially pure aluminum ...
CORROSION BEHAVIOR OF COLD SPRAYED ALUMINUM OXIDE REINFORCED ALUMINUM COATINGS
(Monterey, CA; Naval Postgraduate School, 2021-06)
The selection of materials in the cold spraying process has a significant impact in corrosion resistance. Recognition of this could provide the opportunity to adapt a wide range of coating deposits for different applications ...
MECHANICAL BEHAVIOR OF COLD SPRAYED CU-NI COATING
(Monterey, CA; Naval Postgraduate School, 2021-09)
Cold spray is a developing additive-manufacturing technology well suited as a preventive and corrective measure for metallic materials. The key challenge lies in formulating the optimal multifaceted spray parameters to ...
MECHANICAL AND MICROSTRUCTURAL PROPERTIES OF MARAGING STEEL SAMPLES PRODUCED BY ADDITIVE MANUFACTURING (3D PRINTING)
(Monterey, CA; Naval Postgraduate School, 2020-06)
In recent years, additive manufacturing (AM) techniques have been compared to those of traditional manufacturing (TM) in order to compare and contrast part quality. Selective Laser Melting (SLM) is an AM technique which ...
ENHANCING MECHANICAL PROPERTIES OF COLD-SPRAYED ALUMINUM COATINGS USING GRAPHENE-NANOPLATELET AND MICRO-BORON-CARBIDE REINFORCEMENTS
(Monterey, CA; Naval Postgraduate School, 2022-06)
This study explores the individual and combined reinforcement effects of graphene nanoplatelets (GNP) and micro-boron carbide (µB4C) in cold-sprayed Al matrix composite coatings. High energy ball milling was used to create ...
MICROSTRUCTURAL SURFACE INCORPORATION OF PHASE CHANGE MATERIALS FOR THERMAL MANAGEMENT APPLICATIONS
(Monterey, CA; Naval Postgraduate School, 2022-06)
Thermal management strategies employed to mitigate the detrimental effects of elevated temperatures include the use of heat sinks or spreaders, thermal interface materials, and phase change materials (PCM), among others. ...
ENGINEERING SUPERHYDROPHOBIC BEHAVIOR IN 3D-PRINTED STAINLESS STEEL COMPOSITES
(Monterey, CA; Naval Postgraduate School, 2022-06)
This thesis discusses the wettability of 316L stainless steel composites using carbon nanotubes and manufactured via a selective laser melting. Superhydrophobicity is created through the combination of low surface tension ...
SUBSTRATE AND FEEDSTOCK FACTORS AFFECTING COLD SPRAY COATING ADHESION AND RELATED IMPACTS ON CORROSION
(Monterey, CA; Naval Postgraduate School, 2021-03)
Cold spray technology has the potential to greatly reduce the effects of corrosion on susceptible materials. Lack of adhesion strength is one of the limitations currently preventing cold spray from becoming a dominant ...
EFFECT OF PYROLYSIS PARAMETERS ON SILICON CARBIDE-FORMING COMPOSITE MIXTURES
(Monterey, CA; Naval Postgraduate School, 2021-06)
High-performance ceramics are often used for reusable spacecraft Thermal Protection Systems (TPS). Pre-ceramic polymers provide a suitable route for fabricating silicon carbide (SiC)–based TPS. It is known that different ...
