Abstract: A method is provided for producing an electrically conductive connection between metallic components (2, 6), such as an agitator blade assembly (6) and a drive shaft (2) which have a non-conductive coating (7). In the method an at least partially electrically conductive pasty medium (8) is located in a pocket (12) between the components (2, 6) in contact with metallic portions (9, 10) of the components (2, 6) which are substantially free of any non-conductive coating (7). The connection between the components (2, 6) themselves provide a protection against the pasty medium (8) being accidentally removed from the region in use. For example, the components (2, 6) may be shrink-fitted together to form the connection with the pasty medium (8) located within the area of contact between the components (2, 6) and surrounded by interference fitted contact areas (11) between the components (2, 6) to provide the protection for the pasty medium (8).
