Decorative part made by inlaying
A method is for manufacturing a part including a support provided with at least one hollow filled with an aesthetic element forming a decoration on a face of the part intended to be visible. The method includes providing the support provided with the at least one hollow and providing a preform intended to form the aesthetic element of the part, and inlaying by pressing the preform into the at least one hollow of the support. The preform is made of a crystalline aluminium alloy. The inlaying is carried out at a temperature between the solidus temperature and the liquidus temperature of the crystalline aluminium alloy.
1 . A method for manufacturing a part comprising a support provided with at least one hollow filled with an aesthetic element forming a decoration on a face of the part configured to be visible, said method comprising:
providing the support provided with said at least one hollow and providing a preform configured to form the aesthetic element of the part, said at least one hollow opens out in at least one place on a face of the part configured to be non-visible;
inlaying by pressing the preform into said at least one hollow of the support;
mechanical grinding following the inlaying; and
electrochemical surface treating the aesthetic element following the mechanical grinding,
wherein the preform is made of a crystalline aluminium alloy, and
wherein the inlaying is carried out at a temperature between the solidus temperature and the liquidus temperature of the crystalline aluminium alloy, and
wherein, after the mechanical grinding, said at least one hollow includes several orifices that open out at several places on the face of the part configured to be non-visible, to respectively form more than one contact point for the aesthetic element to supply current across the aesthetic element during the surface treatment,
wherein, after the mechanical grinding, said decoration extends continuously in contact with the face between the several orifices.
2 . The method according to claim 1 , wherein the support is made of a material chosen from among ceramic, sapphire and enamel.
3 . The method according to claim 1 , wherein the support is made of a zirconia-based ceramic.
4 . The method according to claim 1 , wherein the crystalline aluminium alloy is a 7075 alloy.
5 . The method according to claim 1 , wherein the support is preheated prior to the inlaying to a temperature comprised between 300 and 500° C.
6 . The method according to claim 1 , wherein the inlaying by hot pressing is carried out under a load of between 500 and 1000 kg.
7 . The method according to claim 1 , wherein the inlaying by hot pressing is carried out at a temperature comprised between 500 and 650° C.
8 . The method according to claim 1 , wherein each of the several orifices has a different sized opening on the face of the part configured to be non-visible.
