Steel plates undergo electrochemical corrosion and marine organism attachment in seawater, leading to increased navigation resistance (Rising fuel costs), weakened structural strength, and frequent expensive dry dock maintenance
Seawater pipelines, ballast tanks, heat exchangers, and other systems leak due to corrosion, causing shutdowns, safety accidents, and expensive emergency repairs.
Traditional sandblasting and coating maintenance relies on scaffolding and large amounts of labor, with major risks such as high-altitude falls and health damage (Dust), and low efficiency and long cycles.
Inspection of underwater structures and hull plating often requires ships to enter dry dock or hire divers, with high costs and inability to achieve normalization.
lithium source (such as Lioh) in ncm materials is extremely alkaline at high temperature and has high fluidity. We use α-phase strengthened alumina-based composite material, whose crystal phase is extremely stable in this temperature zone and alkaline environment, can effectively block lithium ion diffusion channels.
Aiming at the characteristic of volume shrinkage after sintering of this material, we designed specific inner cavity inclination angle and micro-texture surface, which is convenient for demolding and can reduce contact stress between material and sagger, prevent adhesion.
Laboratory test life: Under simulated working conditions, after 150 consecutive sintering, no cracking appeared, flexural strength retention rate >85%.
Test on sintered materials, key impurity increment did not exceed detection error range.
On a head battery material enterprise production line, average service life increased from about 70 times to 160 times, product magnetic foreign matter qualification rate significantly improved.

Withstand reducing atmosphere and silicon activity during carbonization.
The lithium source (such as LiOH) in NCM materials has strong alkalinity at high temperatures and high fluidity. We use alpha; -The phase reinforced alumina based composite material has a relatively stable crystal phase in this temperature range and alkaline environment, which can effectively block the diffusion channels of lithium ions.
We have designed specific internal cavity inclination angles and micro textured surfaces to address the volume shrinkage characteristics of the material after sintering. This not only facilitates demolding but also reduces the contact stress between the material and the bowl, preventing adhesion.
Laboratory test life: Under simulated working conditions, after continuous sintering for 150 times, no cracking occurred, and the flexural strength retention rate was>85%.
After use, the sintered material was subjected to ICP testing, and the increment of key impurities did not exceed the detection error range.
The flue gas desulfurization device is an auxiliary equipment of thermal power plants, which can prevent air pollution. The flue gas desulfurization device of coal-fired power generation equipment contains chlorides that cause environmental pollution. The use of commonly used N08904 (904L), N08367/AL-6XN, S31254/254SMO, N08926 (1.4529) super austenitic stainless steel in environments with chloride ion concentrations exceeding 10000 ppm can reduce equipment wear and tear costs and extend service life.
The materials of the exhaust gas desulfurization device are exposed to exhaust gas containing sulfur and chlorine for a long time, and there may also be high humidity corrosion loads due to seawater. Common types of corrosion in abandoned desulfurization equipment include uniform corrosion, intergranular corrosion, pitting corrosion, crevice corrosion, etc. Choosing appropriate materials is the key to extending the service life of exhaust gas desulfurization devices. Our company provides nickel based alloys and special stainless steels such as NO8926/1.4529 NO8367/AL-6XNS31254/254SMO 31alloy 2507 for the manufacturing of ship engine exhaust gas desulfurization devices, which play a crucial role in wet corrosion environments.
