Bending strength of welded joints in TMCP steel square tubular profiles "T" connexions
Dalcin, Rafael Luciano; Machado, Ivan Guerra; Gonzalez, Arnaldo Ruben; Mazzaferro, Cintia Cristiane Petry (2016) [Artículo de periódico]The use of DOMEX 700 MCTM steel weldments is still little explored, due to some concern of the validity of the rules imposed by several standards and Codes for this class of steel. This material has low ductility and ... -
Comparative analysis of the friction and microstructural properties of WC-10Co-4Cr and Cr3C2-25NiCr coatings sprayed by high-velocity oxy-fuel (HVOF)
Marques, Angela Selau; Dalcin, Rafael Luciano; Oliveira, Leonardo Fonseca; Silva, Lucas Alves Vitor da; Santos, Giovanni Rocha dos; Rocha, Alexandre da Silva (2018) [Artículo 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: ... -
Efeitos da energia de soldagem e consumível sobre a resistência à flexão simples de juntas soldadas em perfis tubulares de aço TMCP
Dalcin, Rafael Luciano; Machado, Ivan Guerra; Gonzalez, Arnaldo Ruben; Mazzaferro, Jose Antonio Esmerio (2016) [Artículo de periódico]A introdução dos aços fabricados por processamento termomecânico controlado (TMCP) demandou maiores propriedades mecânicas e metalúrgicas das juntas soldadas sobre eles produzidas. Em função desses fatores, a energia de ... -
Influence of plasma nitriding with a nitrogen rich gas composition on the reciprocating sliding wear of a DIN 18MnCrSiMo6-4 steel
Dalcin, Rafael Luciano; Rocha, Alexandre da Silva; Castro, Victor Velho de; Oliveira, Leonardo Fonseca; Neves, Júlio César Klein das; Silva, Carlos Henrique da; Malfatti, Célia de Fraga (2021) [Artículo de periódico]In this study, the sliding wear of a DIN 18MnCrSiMo6-4 continuous cooling bainitic steel plasma nitrided with a nitrogen rich gas composition was investigated. To evaluate the influence of processing time and temperature ... -
Microestrutura e propriedades de desgaste do aço bainítico de resfriamento contínuo DIN 18MnCrSiMo6-4 nitretado a plasma em diferentes temperaturas
Dalcin, Rafael Luciano; Oliveira, Leonardo Fonseca; Rocha, Alexandre da Silva; Malfatti, Célia de Fraga; Hidalgo, Gelsa Edith Navarro; Epp, Jérémy; Zoch, Hans-Werner (2020) [Artículo de periódico]Os novos aços bainíticos de resfriamento contínuo (CCBS) são uma excelente alternativa quando se requer elevada dureza, tenacidade e resistência à fadiga. Contudo, estima-se que a taxa de desgaste dos CCBS seja insuficiente ... -
Microstructure and wear properties of a low carbon bainitic steel on plasma nitriding at different N2-H2 gas mixtures
Dalcin, Rafael Luciano; Rocha, Alexandre da Silva; Castro, Victor Velho de; Neves, Júlio César Klein das; Silva, Carlos Henrique da; Torres, Ricardo Diego; Nunes, Rafael Menezes; Malfatti, Célia de Fraga (2022) [Artículo de periódico]For the first time, the influence of gas mixture on first damage resistance of a plasma nitrided DIN 18MnCrSiMo6-4 bainitic steel was investigated. Samples were nitrided at 500 °C with three different N2 -H2 gas mixtures, ... -
