■任意の形状に加工するには強度が不足している。■Insufficient strength to process into arbitrary shapes.
■例えばＣｕ部材をロウ付接合した場合に、Ａｌの一部
がＣｕ部材中に拡散して、ロウ材の初期組成からずれて
しまい、ロウ材の厚みにもよるが接合部にクラックが生
じることがある。■For example, when Cu parts are joined by brazing, some of the Al will diffuse into the Cu parts, causing deviations from the initial composition of the brazing material, and cracks may occur at the joint, depending on the thickness of the brazing material. There is.
■原料を溶射することから、原料の損失があり、また設
定初期組成と、出来上がり組成との間に違いが生じる問
題がある。■Since raw materials are thermally sprayed, there is a loss of raw materials, and there is also a problem that there is a difference between the initial composition and the finished composition.
