Abstract
아크 금속용사 공법을 활용한 EMP 차폐기술을 개발하기위하여 국내에서 사용되는 3종류의 금속용사 장치의 시공성능을 평가하였다. MS, KMS, HMS에서 용사금속의 부착량은각각 58.32%, 64.66%, 87.62%로 나타났다. 또한, 1시간당시공면적(m2/h)은 MS가 14.3, KMS가 19.25, HMS가22.16으로서 나타났으며, HMS공법의 경우 Φ1.6mm의 선재 사용, 용사면적 80mm 형성, 반선속도 18m/min 사용과함께 금속용사 시공시의 비산량이 대폭 작아졌기 때문으로판단된다. 따라서, 시공성능 측면에서 HMS공법이 EMP차폐용 아크 금속용사공법으로 가장 적합하다고 판단된다.
The arc thermal metal spraying method (ATMSM) has been used in Korea to improve the electromagnetic pulse(EMP) shielding effect of building and infrastructure by three machines of MS, KMS and HMS (Metal Spray, KoreaMetal Spray, High-frequency Meta Spray). The adhesion ability of sprayed metal was found to be 58.32, 64.66 and87.62% for MS, KMS and HMS, respectively. The metal sprayed area per hour of MS, KMS and HMS was calculatedand found to be 14.3, 19.25 and 22.16m2/h, respectively. The HMS showed the highest metal spray area attributed tothe diameter of metal wire i.e. 1.6mm which sprayed 80 mm with 18 m/min. There was minimum loss of metal andthe highest efficiency by HMS compared to others. Therefore, it is suggested to use HMS for metal spraying byATMSM to enhance the EMP shielding effect.
