Analysis of wear in organic and sintered friction materials used in small wind energy converters
(2008) [Artigo de periódico]Wind energy converters of small size used in isolated units to generate electrical energy must present low maintenance cost to such facilities economically viable. The aspect to be analyzed in cost reduction is the brake ... -
Comparative analysis of the friction and microstructural properties of WC-10Co-4Cr and Cr3C2-25NiCr coatings sprayed by high-velocity oxy-fuel (HVOF)
(2018) [Artigo de periódico]In this study, coatings WC-10Co-4Cr and Cr3C2-25NiCr were deposited on the AISI H13 steel by oxy-fuel Thermal spraying (HVOF). This coating increases the wear resistance of surfaces subjected to severe conditions, such as: ... -
Comparative study of jet slurry erosion of martensitic stainless steel with tungsten carbide HVOF coating
(2019) [Artigo de periódico]This work evaluates the behavior of a martensitic stainless steel (AISI 410) thermally treated by quenching and tempering with a tungsten carbide (86WC-10Co-4Cr) coating obtained by high-velocity oxygen fuel (HVOF) thermal ... -
A comparison of microstructural, mechanical and tribological properties of WC-10Co4Cr - HVOF coating and hard chrome to use in hydraulic cylinders
(2018) [Artigo de periódico]In order to obtain a wear and oxidation resistant surface, hydraulic cylinders are commonly coated with electrodeposited hard chromium. However, due to the wear, this type of coating exhibits a gradual increase of the ... -
