  • Publication number: 20210291298
    Abstract: The present invention relates to a method for manufacturing a joint structure of dissimilar materials. The method includes forming a low-temperature thermal spray coating on at least a part of a surface of an aluminum or aluminum alloy material by low-temperature thermal spraying a metal powder of at least one metal selected from the group consisting of ferritic stainless steel, austenitic stainless steel, and ferritic and austenitic two-phase stainless steel, overlapping the aluminum or aluminum alloy material and a steel material such that the low-temperature thermal spray coating and the steel material face each other, and joining the low-temperature thermal spray coating and the steel material by a laser welding from a steel material side.

  • Publication number: 20190291202
    Abstract: A joint structure including a first member, a second member superposed on the first member, a steel insertion member, and a welded part formed on an insertion tip of the insertion member. Each of the first member and the second member includes a high tensile strength steel. The steel insertion member is held by the second member in a state of having been inserted toward a superposition surface between the first member and the second member from a surface of the second member opposite the superposition surface. A carbon equivalent Ceq of the insertion member is lower than a carbon equivalent Ceq of the second member, where Ceq=C+Si/30+Mn/20+2P+4S.
