Description
Technical Field
The invention relates to the technical field of glass molding, in particular to a molding for manufacturing an optical glass element and the optical glass element.
Background
At present, the phenomena of mucosa, coating shedding and the like are easy to occur in the molding process of high-refractive-index optical glass elements (lead (Pb) series, Bismuth (Bi) series and the like) with refractive index nd larger than 1.8, and the service life of a mold is short. Most of the existing patents develop a plating layer aiming at the low refractive index glass molding, and mainly use diamond-like carbon film or binary components such as Platinum (Pt) Pt-Ir, Re-Ir, etc. as main components. The coatings developed for the molding of high index optical glass elements are lacking.
The coating developed for molding the low refractive index optical glass element is very likely to cause mucosa failure when applied to molding a high refractive index optical glass element (Pb series, Bi series and the like with the refractive index nd larger than 1.8), and is not suitable for molding the high refractive index optical glass element. In the prior art, the quaternary coating developed for the molding of the high-refraction optical glass element is a single functional layer without a transition layer, and because the difference of the interface characteristics of the substrate material and the coating material is large, the quaternary coating is easy to fall off and lose efficacy in the repeated molding process and has short service life; and the plating material contains Pt, which is easy to react with Pb and Bi to cause mucosa failure.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a forming mold for manufacturing an optical glass element, the mold includes a substrate and a plating layer on the surface of the substrate, the plating layer includes a transition layer and a functional layer laminated in sequence from the surface of the substrate; a transition layer 2 and a functional layer 3 are sequentially attached to the surface of the mold 1; the transition layer 2 is a ceramic transition layer comprising carbide or nitride; the functional layer 3 is a precious metal alloy functional layer consisting of Mo, Re, Ir and Rh or consisting of Mo, Re, Ir and Ru.
Specifically, the transition layer 2 is a ceramic transition layer comprising WC or CrN; the thickness a of the transition layer 2 is 30nm-200 nm. Preferably, the transition layer 2 is a ceramic transition layer comprising tungsten carbide and has a thickness of 70nm to 100nm, and the transition layer 2 is a ceramic transition layer comprising chromium nitride and has a thickness of 100nm to 200 nm.
Specifically, the functional layer 3 includes 10 to 50 at% of Mo, 5 to 50 at% of Re, 10 to 50 at% of Ir, and 10 to 50 at% of Ru or Rh. The thickness of the functional layer is 200nm-1000 nm.
Please refer to table 1 and table 2, which show the analysis test data performed in one embodiment:
table 1:
table 2:
wherein component/at% represents the atomic percentage of the component.
Wherein, the SF57 glass is high-refractive index glass with the model SF57, and the refractive index nd is 1.84666.
Among them, test data in table 1 when the transition layer component is WC, and test data in table 2 when the transition layer component is CrN.
As can be seen from the data in tables 1 and 2, simply including the Re and/or Ir containing, or Pt and/or Ir, or Pt containing multiple alloy plating, both performed poorly during the molding process; in the case of the functional layer components 20 at% Mo, 10 at% Re, 30 at% Ir and 40 at% Rh, the WC transition layer thicknesses are excellent in the test data of 30nm, 50nm, 70nm, 100nm, 150nm and 200nm, respectively, and in the case of the WC transition layer thickness of 70nm, in the case of the following complete functional layer-containing components: the functional layer comprises 0-50 at% of Mo, 0-50 at% of Re, 10-50 at% of Ir and 10-50 at% of Ru or Rh. In the case of functional layer components of 20 at% Mo, 10 at% Re, 30 at% Ir and 40 at% Rh and thicknesses of 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900nm and 1000nm, respectively, the CrN thicknesses of 100nm, 120nm, 140nm, 160nm, 180nm and 200nm, respectively, are excellent in the test data, and in the case of CrN thicknesses of 100nm to 200nm, are excellent in the following case of complete inclusion of the functional layer component: the functional layer comprises 0-50 at% of Mo, 0-50 at% of Re, 10-50 at% of Ir and 10-50 at% of Ru or Rh.
In addition, the invention also provides an optical glass element which is molded by adopting the mold.
Compared with the prior art, the forming die for manufacturing the optical glass element provided by the invention has the advantages that the transition layer and the functional layer which are sequentially laminated on the surface of the substrate are used as the coating, and the coating material does not contain Pt, so that the problem that the coating is easy to react with Pb and Bi in high-refractive-index optical glass to cause mucosa in the prior art is effectively solved; the introduction of the transition layer obviously increases the binding force between the coating and the surface of the die substrate, effectively prevents the coating from falling off and losing efficacy, and prolongs the service life of the die. According to the test data, the quaternary coating MoIrReRh or MoIrReRu still can be kept intact and not fall off after the SF57 glass is molded for 500 times, the quaternary coating MoIrReRh or MoIrReRu has high falling-off resistance and anti-sticking performance, and a die with the quaternary coating has long service life.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
