The laser deposited additive manufacturing is of a revolutionary significance for aircraft landing gear manufacturing.It has many technical vantages

such as breaching restriction of material specification

reducing waste of original material

and shortening manufacturing time. This technology has obvious advantage and application prospects on rapid trial-manufacture for the future aircraft undercarriage. At present

the key technologies of laser deposited A-100 steel such as forming process

quality control and so on have been breached through. The undercarriage formed by laser deposition has achieved leading application on aircraft. Mechanical properties of parts reached almost that of the forgings. Some keys such as strategy of forming process

control of heat treatment

non-destructive testing

surface strengthening and integrated evaluation

need to be further broken through and solved for extended application of this technology.
