Abstract

The invention relates to the fields of metal material accelerated corrosion and corrosion fatigue, in particular to equipment for implementing synchronous dry-wet alternate accelerated corrosion in aloading process and application thereof. In the equipment, a temperature control device and a humidity control device sense temperature and humidity in a corrosion fatigue tank, and transmit signals to a control system, and the control system sends an instruction for adjusting the temperature and humidity in the corrosion fatigue tank to implement temperature control and humidity control. Simultaneously, a loaded sample in the corrosion fatigue tank is regularly sprayed through the instruction of the control system so as to implement dry-wet alternate corrosion. The equipment can assist fatigue testers and slow strain equipment to implement the synchronous dry-wet alternate corrosion of the sample in the fatigue, tensile or slow strain process, also can be used for simulating temperature control and humidity control corrosion fatigue, tensile or slow strain tests under different weather conditions, and temperature control and humidity control dry-wet alternate corrosion tests, and implements the synchronous dry-wet alternate accelerated corrosion in the corrosion fatigue process and in the slow strain process.
