Abstract

membro estrutural de uma liga de magnésio. é fornecido um membro estrutural de uma liga de magnésio possuindo excelente resistência à corrosão. o membro estrutural de uma liga de magnésio inclui um substrato de liga de magnésio que contém mais do que 7,5% em peso de al e uma camada anticorrosiva formada em um superfície do substrato pelo tratamento de conversão química. o substrato contém um precipitado, tipicamente, partículas dispersas no mesmo. as partículas são feitas de um composto intermetálico contendo pelo menos um de al e mg e têm um tamanho médio de partícula de 0,05 m ou mais e 1 m ou menos. a área total das partículas representa entre 1% da área ou mais e 20% da área ou menos. a camada anticorrosiva inclui uma subcamada inferior e uma subcamada de superfície no substrato nesta ordem. a subcamada de superfície é mais densa do que a subcamada inferior. o substrato do membro estrutural de uma liga de magnésio tem alta resistência à corrosão por causa de um alto teor de al. o membro estrutural de uma liga de magnésio tem excelente resistência à corrosão por causa da subcamada densa no lado frontal da camada anticorrosiva, que impede que um líquido corrosivo atinja o substrato. a subcamada inferior porosa pode reduzir a tendência da camada anticorrosiva de separar do substrato, por exemplo, quando de um impacto e permite que o membro estrutural de uma liga de magnésio possa conservar uma alta resistência à corrosão.
