The scale formed on pure Ti is exclusively TiO2 regardless of temperature, while the scales formed onTi3Al and Ti3Al+TiAl were duplex and always spalled after cooling, consisting of the outer-layer of most TiO2 and the inner-layer of most TiO2, Al2O3, and minor Ti(subscript 1-x)S. The formation of Al2O3 is responsible for the reduction in the corrosion rates of Ti-Al alloys as compared to those of pure Ti.

纯Ti在800～1000℃的腐蚀生成物皆是TiO2，而Ti3Al和Ti3Al+TiAl则形成两层易剥落的腐蚀物，包括外层的TiO2，及内层多量TiO2和少量的Al2O3和微量的Ti(下标 1-x)S，其中，Al2O3的生成是造成Ti3Al和Ti3Al+TiAl合金腐蚀速率较纯Ti为低的主因。
