Constante de mola de molas cerâmicas injetadas a baixa pressão

Abstract: INTRODUÇÃONos últimos anos houve um crescente interesse na fabricação das molas cerâmicas, visando aplicações que exijam resistência à corrosão, tanto em temperatura ambiente como em alta temperatura [1][2][3][4][5][6]. Molas e enrolamentos cerâmicos têm sido obtidos por usinagem de cilindros, por extrusão de misturas de cerâmicas com polímeros ou pelo processo sol-gel [1][2][3][4][5][6]. Enquanto o primeiro processo é flexível, mas de custo elevado, nos dois últimos existe a dificuldade de extrair o ligante s… Show more

“…The literature reports the realization of springs from numerous structural ceramics. In addition to highstrength oxide materials, such as alumina, 5,[12][13][14] alumina toughened zirconia (ATZ), 11 zirconia toughened alumina, 15 tetragonal zirconia polycrystals (TZP), 12 and partially stabilized zirconia (PSZ), 4,11 the spectrum of materials also includes silicon nitride 2,10,11 and graphite. 7 Great potential is seen for springs made of ceramic composites such as C/SiC 16 and multi-composites containing mullite, SiC particles, and SiC whiskers.…”
