  • 이번 실험에서는 건식 도금방법을 이용한 알루미늄 도금강판의 조성 및 두께에 따른 내식성 평가를 염수분무 실험을 통해 측정하였다. 실험 결과 도금 조성 내 Silicon의 조성이 증가할수록, 일반적인 건식도금 방법보다 조직 성장 시 도금 층에 각을 주어 도금하는 것이 내식성을 향상시키는 것으로 관찰되었다.

  • We propose the vehicle maintenance support system to alarm consumable replacement reminders to the vehicle owner. Since the delayed replacement of the consumables makes the condition of the vehicle worse, it is crucial to replace consumables in a recommended period. The vehicle maintenance support system alarms the replacement time, which is set by the vehicle owner, based on the mileage of the installed vehicle. It integrates speed information acquired from the Controller Area Network interface for communication between Electronic Control Unit and instrument panel, exposed at the On Board Diagnostics-II port, to calculate the vehicle mileage. By this, there is no additional wiring required for the system. We verify the system has only 0.28% error by comparing the mileage on the system with the instrument cluster on the vehicle. It automatically enters low-power mode consuming 15mW, which is a negligible amount for the typical conditions of the car, to prevent the vehicle battery from discharging when the ignition is off.
