Abstract

a presente invenção refere-se a uma seção de tensão residual de compressão (50) que possui a tensão residual de compressão da superfície de um arame (40) a uma primeira profundidade (d1) formadando entre as seções curvas finais (12a, 12b) de uma mola espiral (12). a seção de curva final (12a) inclui uma primeira seção (12a1), uma segunda seção (12a2), e uma terceira seção (12a3). a primeira seção (12a1) está sempre em contato com um assento de mola independentemente da carga aplicada à mola espiral (12). a segunda seção (12a2) está em contato com o assento de mola quando a carga aplicada à mola espiral (12) é grande, e está separada do assento de mola quando a carga é pequena. a terceira seção (12a3) sempre está separada do assento de mola, independentemente da magnitude da carga. na seção de curva final (12a), em uma região que inclui a segunda seção (12a2), uma seção de tensão residual profunda (51) é formada por jateamento ultrassônico. a seção de tensão residual profunda (51) possui uma tensão residual de compressão de uma superfície do arame (40) a uma segunda profundidade (d2) mais profunda que a primeira profundidade (d1).
