Abstract:
1. A part for an article of equipment, the part comprising: a fluid conducting first region including a corrosion resistant first material selected from the group consisting of zirconium and zirconium alloys; a fluid conducting second region including a second material selected from the group consisting of titanium, titanium alloys, and stainless steel; and a fluid conducting third region including a third material selected from the group consisting of titanium, titanium alloys, and stainless steel; wherein the second region and the third region are directly joined to opposite ends of the first region by a friction welding technique to form a unitary fluid conducting part; wherein a weld region formed by friction welding the second region to the first region is substantially free of alloys and interdiffusion layers of the corrosion resistant first material and the second material; and wherein a weld region formed by friction welding the third region to the first region is substantially free of alloys and interdiffusion layers of the corrosion resistant first material and the third material.
