Overview on Rapid Investment Casting of Pattern Making Process

[Vol. 05 (01), December, 2024, pp. 107-111]

RIC i.e. Rapid investment casting is a manufacturing process that uses Additive Manufacturing (AM) technologies to create master patterns. Common techniques for producing wax and non-wax patterns contain FDM (Fused Deposition Modeling), ink-jet rapid prototyping, and Stereolithography (SLA). The characteristic of RIC products is influenced by the abilities and inabilities of each AM technology and the materials used. In addition to pattern materials like wax, thermoplastic, ice, and photopolymer, this paper evaluates the benefits and drawbacks of FDM, MMII (Model Maker II), SLA, and RFP (Rapid Freeze Prototyping). The evaluation indicates that SLA yields the highest quality patterns, while FDM (Fused Deposition Modeling) is the most economical option. Additionally, new challenges in materials, including how ice patterns develop, have been identified and require further research. Additionally, the paper reviews recent models for the investment casting process's numerical simulations, noting that most studies focus on estimating the time needed for solidification, hot spots, areas of hot tearing, and macro and micro porosities.

Corrosion effect on ferrous alloys in the Deep-Sea water and different Sea Areas

[Vol. 05 (01), December, 2024, pp. 112-114]

The paper prepares for corrosion of ferrous alloys in Deep-sea water. It is undergoing uniform corrosion without forming an acquiescent layer is related to the amount of dissolved complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances are sodium, chloride, magnesium, sulphate, and calcium. Some atmospheric gases, inorganic and organic materials are also included with the water of Ocean. The performance of some ferrous alloys measured at the depths of 500, 1000, 3000, and 5300 m in the Indian Ocean, South China Sea & Western Pacific Ocean, the atomic integration qualitative analysis and found that the corrosion product present on mild steel Alloys. It has also observed in deeper waters, no macrofouling was visible, there for corrosion was not related to any biological product but mainly to the micro-chemical reaction of these alloys with sea water. Corrosion behaviour of metallic materials is of higher for Strong degradation of a permanent implant would lead to failure by loss of the device integrity; for high-corrosion resistant metals and alloys that are typically used in such applications, strong active dissolution is, however, not expected.
