【Abstract】 Aluminum alloys LD10 and LY12 were implanted with nitrogen ions by Plasma lmmersion lon lmplantation (P111) and dose range of 2×1017～1×1018N＋．cm-2. The depth profile of nitrogen and structure of the implanted sudece layer were investigated by AES. TEM and TED. Hardness and elastic modules vs. depth were measured with a nanoindenter, and wear tests were carried out on a ball-on-disc wear testing machine. The results reveal that implanted nitrogen combines with aluminum to form AIN precipitations, the crystallographic relationship between the AIN precipitation and Al matrix is: {0001}AIN更多还原
