Abstract: The invention relates to a method for carrying out the diffusion treatment on the coating of engineering parts resistant to marine climate. The method comprises the following steps: 1. pre-treating the parts; 2. pre-heating the parts in a protective atmosphere furnace; 3. immersing the pre-heated parts in a plating solution in away that the parts are rotated in the submerging process; 4. undergoing the diffusion treatment, particularly, putting the immersion-plated parts into a vacuum furnace, holding at 800 to 950 DEG C for 1 to 3 hours, then reducing the temperature gradually and taking out the parts, and forming a diffusion layer on a substrate through the diffusion of atoms at the interface to achieve the metallurgical combination between the coating and the substrate. The parts treated by the method of the invention are highly resistant to corrosion and scouring erosion under the condition of marine climate.

Abstract: In a process for the cooligomerization of olefins, an olefin starting material comprising olefins having n carbon atoms and olefins having 2n carbon atoms is reacted over an olefin oligomerization catalyst to give a reaction product. The process is carried out under such conditions that the conversion of olefins having 2n carbon atoms is less than 10%. Both the cooligomer having 3n carbon atoms and the olefin having 2n carbon atoms which has been separated off from the reaction product have a high hydroformylatability.
