A method of fabricating a torque converter, including: forming a turbine shell including a first annular portion with a first surface having a first roughness and forming a radially outermost portion of the turbine shell; fixing a first plurality of blades to the turbine shell; forming an impeller shell including a second annular portion with a second surface having a second roughness; fixing a second plurality of blades to the impeller shell; removing at least a portion the first or second surface without the use of particulate matter or a liquid; increasing the first or second roughness of the first or second surface from which the at least a portion is removed; applying an adhesive to the first or second surface from which the at least a portion is removed; and bonding, with the adhesive, friction material to the first or second surface. 种制造扭矩变换器的方法，包括：形成包括第环形部分的涡轮壳体，所述第环形部分包括具有第粗糙度的第表面且形成涡轮壳体的径向最外部分；将多个第叶片固定至涡轮壳体；形成叶轮壳体，其包括具有第二表面的第二环形部分，所述第二表面具有第二粗糙度；将多个第二叶片固定至叶轮壳体；在不使用颗粒物或液体的情况下去除第或第二表面的至少部分；增加被去除了所述至少部分
