Abstract
Official abstract text for this publication.
A simple water jet peening method is usable for a smaller device, and allows use of an existing underwater washing machine. The method includes immersing an object in a water based washing liquid in a washing bath to have a processing surface at a distance of at least 100 mm and less than 300 mm from a liquid surface of the water based washing liquid, and jetting the water based washing liquid from a nozzle downward toward the object in the water based washing liquid contained in the washing bath.
First claim
Opening claim text (preview).
What is claimed is: 1 . A water jet peening method, comprising: immersing an object in a water based washing liquid in a washing bath to have a processing surface at a distance of at least 100 mm and less than 300 mm from a liquid surface of the water based washing liquid; and jetting the water based washing liquid from a nozzle downward toward the object in the water based washing liquid contained in the washing bath. 2 . The water jet peening method according to claim 1 , wherein jetting the water based washing liquid includes imparting compressive residual stress in the processing surface. 3 . The water jet peening method according to claim 1 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid at a jet pressure of at least 15 MPa and not more than 35 MPa. 4 . The water jet peening method according to claim 1 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid while the nozzle has an end at a distance of at least 50 mm and not more than 250 mm from the liquid surface in the washing bath. 5 . The water jet peening method according to claim 1 , wherein the water based washing liquid is free of a surfactant. 6 . The water jet peening method according to claim 5 , wherein the water based washing liquid contains an amine compound. 7 . The water jet peening method according to claim 1 , wherein the object comprises an aluminum alloy. 8 . The water jet peening method according to claim 1 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid while allowing a circulation obstruction to obstruct circulation of the washing liquid in the washing bath to reduce liquid surface waves. 9 . The water jet peening method according to claim 2 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid at a jet pressure of at least 15 MPa and not more than 35 MPa. 10 . The water jet peening method according to claim 2 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid while the nozzle has an end at a distance of at least 50 mm and not more than 250 mm from the liquid surface in the washing bath. 11 . The water jet peening method according to claim 3 , wherein jetting the water based washing liquid from the nozzle includes jetting the washing liquid while the nozzle has an end at a distance of at least 50 mm and not more than 250 mm from the liquid surface in the washing bath. 12 . The water jet peening method according to claim 2 , wherein the water based washing liquid is free of a surfactant. 13 . The water jet peening method according to claim 3 , wherein the water based washing liquid is free of a surfactant. 14 . The water jet peening method according to claim 4 , wherein the water based washing liquid is free of a surfactant. 15 . The water jet peening method according to claim 12 , wherein the water based washing liquid contains an amine compound. 16 . The water jet peening method according to claim 13 , wherein the water based washing liquid contains an amine compound. 17 . The water jet peening method according to claim 14 , wherein the water based washing liquid contains an amine compound. 18 . The water jet peening method according to claim 2 , wherein the object comprises an aluminum alloy. 19 . The water jet peening method according to claim 3 , wherein the object comprises an aluminum alloy. 20 . The water jet peening method according to claim 4 , wherein the object comprises an aluminum alloy.
