Abstract: Corrosion inhibition of mild carbon steel, CT3,  in 1.0 M HCl solution by iodide  (with different concentrations, from 0.1g/l to 5.0g/l), mix of caffeine and iodide was investigated by electrochemical methods and micro surface observations (SEM). Experiment result showed that: (1) as the concentration of iodide increases, the inhibition efficiency increases;  Iodide acts as a mix – type inhibitor but inhibits anodic reaction is predominant. (2) Mix of 1.0 g/l iodide ang caffeine acts as a typical mix – type inhibitor. the current densities of both of anodic and cathode are decline when concentration of caffeine is 1.0 g/l or more. Inhibition efficiency max is approximately 96% at concentration of 5.0 g/l caffeine, the inhibition efficiency maintained relatively stable within 5 days.

Weld Parameters

Linear Friction Welding (LFW) is well adapted to produce titanium aircraft engine and structure parts, as an alternative to machining from solid, from forging or from electron beam welded blanks. The process can be described through a small number of mechanical variables: the amplitude and frequency of oscillation motion, the contact pressure and the axial displacement resulting of hot material flowing outside of the joint interface. Nonetheless, because of the high speeds and loads, the correct control and monitoring of linear friction welding requires special care on machine and tooling design. The main principles of LFW machine design are described, with a special focus on the consistency between process quality requirements and machine characteristics: the static and dynamic machine behavior, the control system performance, the sensor technology and the tooling clamping solutions shall allow a good control of the weld parameters and an accurate monitoring of the physical phenomena at the joint interface.
